Java name
Message to Sdornan: I made the "09:09, 31 August 2007" edit to document how the final name was chosen. However I noticed you changed the meaning of the sentence when cleaning it up in one of your following edits (it originally explained that the project started in June 91, but your edit make it sounds like what happened in June 91 was the decision on the final name). I am going to change the sentence to something a bit different, if you don't mind. -- R. Duxx 76.173.67.9 06:23, 1 September 2007 (UTC)

Languages Influenced By
It is apparent that Java was influenced by the Mesa language developed by Xerox. Coder1024 03:37, 2 May 2007 (UTC)

Influenced by Lisp and C#?
216.252.85.18 added Lisp and C# to "influence by" in the info box. I've reverted those, as obviously the chronological order is incorrect for Java to be influenced by C#. While Gosling has mentioned Lisp, along with a number of other languages not listed, as a language from which lessons were taken, I think it is a stretch to include Lisp in the infobox. I consider the infobox to list the languages which had a strong influence that can be traced from the features and philosophy of the language. Otherwise you rightly might have to include every preceeding language as an influencer. I welcome any other opinions on the matter. —Doug Bell talk 04:12, 21 February 2007 (UTC)


 * Late addition to this thread: what does "influenced by" mean in the first place? I personally have a very strong expectation that a language "influence" refers to the language at the conception of its most essential features and characteristics.  I expect the influence tree to be structured as a DAG, except in cases where the inception of the languages was contemporaneous to such a degree it amounted to growing up in the same crib.  I can't even come up with such an example off the top of my head: Ruby postdated Python by just long enough to suspect Python wasn't much influenced by Ruby.  (Second question: does "influence" include negative influences such as "no way we do that stupid thing they did over there?")
 * The kinds of minor influences being proposed here make the idea of an influence non-encyclopedic, degrades the concept almost to a trivia section. The influence can be ridiculously minor, even if a reference is found saying "X was aware of Y".  A language feature might have been on the "todo" list for a decade before making it to the top of the list, by which point another language has delivered the feature first, whereupon the syntax is borrowed as a convenience to people who work across language boundaries.  Probably every spoken human language in the world that has a term for "satellite dish" has copped at least one Anglicism.  Worthless.  MaxEnt (talk) 17:08, 10 December 2007 (UTC)


 * Java is certainly influenced by C#, witness the slew of new language feature in 1.5, after C#, which was in direct competition, brought some of its own missing from Java. It'd be pretty hard to source, though... As for Lisp, I agree. -- int19h 05:51, 21 February 2007 (UTC)


 * Many of those relatively minor language changes have been under discussion for a long time. I don't think it's accurate to say that they were influenced by C#, but even if they were, the language itself is not, and the additions are minor. —Doug Bell talk 06:10, 21 February 2007 (UTC)


 * The influence by C# was already there (note that user 216.* didn't change it), and was properly sourced and explained. (Unlike the other influences, shouldn't we explain about Eiffel's and SmallTalk's influence too?) The chronological order has little to do with which language can influence which. Language gain features that existed in other languages all the time, no matter which langauge came out first. I think it's pretty obvious  that Java was influenced by C#. Most of the major feature differences between C# and Java were implemented in Java 5. And that's really not a Bad Thing, if you ask me. All of the features significantly changed the language, and the standard library would probably have been designed very differently in the presence of enums, annotations, autoboxing, and even varargs. (Generics is correctly not included in the list of features, since it has a completely different origin and implementation.) Anyway, about Lisp, I don't really recognize its influence in Java. This is the first time I heard about it. - Chip Zero 09:36, 21 February 2007 (UTC)


 * Other than generics, the features implemented in Java 5 were primarily "syntactic sugar" in that they didn't add any functionality, only provided alternative means of writing the same thing in the source code. They really are quite minor additions to the language, nothing on the order of the inner classes.  Generics had been discussed since the early days of Java, well before C# was even a rumor (it was JSR 14, submitted in 1999).  Whatever "influence" C# had on Java was quite minor.  You can make a case that annotations had a significant impact on the Java environment because of how they are leveraged by tools, but their impact on the language itself is minor.  Besides, my take on the languages listed in the infobox is that it means "creation influenced by", although as I point out above, it wouldn't really matter if it just means "influenced by". —Doug Bell talk 09:56, 21 February 2007 (UTC)
 * Besides, you can't claim that varargs and enums were influenced by C#—those were features of C, and were not implemented in a similar fashion in Java as in either C or C#. —Doug Bell talk 10:10, 21 February 2007 (UTC)


 * Yes, most of these features are strictly syntactic sugar. But then again, most of the Java language features are syntactic sugar over the core language (such as inner classes, most control flow statements,,  ,  , ...). It's the sugar that makes the language. And don't underestimate these features, they are all powerful features for building good application frameworks (minus perhaps the enhanced for loop). Auto-boxing for example changes the way we look at collections and methods that take a   argument. Enums give increased typesafety with the simplicity that the old integer constants used to have. Varargs allows you to write new kinds of methods, such as the new String formatting method. (Which is implemented on basis of a typesafe array, unlike in C BTW.) Yes, technically you could do these things before, but it was all so hard or inconvenient that nobody ever did it. And yes, annotation obviously go beyond syntactic sugar, and allow all kinds of funny things such as the XMLSerializer for C# illustrated. Finally, my take on "influences", is just that, other languages that had a (notable) influence on the design of the language at one point or another. The computer languages history graph illustrates this nicely. Likewise, Ruby is also stated as an influence on C# here, even if it only influenced C# 2.0. - Chip Zero 10:41, 21 February 2007 (UTC)


 * I still disagree with listing C# as an influence. For now, I've removed the attribution of varargs and enums from the C# reference because these were clearly features from previous lanaguages that had been discussed as additions to Java long before C#.  I don't see the connection for annotations either as these had been informally done using Javadoc comments for some time prior to be adopted as a language feature.  I think the connection to C# is extremely thin and certainly falls below the level of influencer. —Doug Bell talk 19:18, 25 February 2007 (UTC)


 * I have to agree with you about enums; they have a different functionality and implementation in the two languages (flaggable enums vs. enums with members). (Although one could argue that they'd never have been added if it wasn't for C#, since enums have been around for ages now.) Java varargs however &mdash; even though the name comes from C &mdash; work exactly the same in Java as they do in C#, albeit with a different syntax. I hate to re-iterate myself, but both are implemented using a heap-allocated typesafe array as the underlying data structure. What other statically typed languages do you know do this? - Chip Zero 15:35, 26 February 2007 (UTC)


 * With enums, they had been used in Java as a pattern prior to C# being a twinkle in the eye of Microsoft. (I may actually have been the first to propose this pattern in 1996.)  Like many of the added language features, formallizing it in the language was the result of careful consideration.  I would certainly put varargs in this category as well, although I suppose the C# implementation of the feature my have been suggestive.  Java is defined as much by what features are not in the language as it is by the features that are.  The only one of the added features I think likely to have been directly influenced by C# is the autoboxing/unboxing of primitive types into their corresponding primitive wrapper classes. —Doug Bell talk 16:06, 26 February 2007 (UTC)


 * Well the thing is, in C# enums are really just primitive types, with language and framework support (see comparison of C# and Java). This means that they can be combined using the bitwise OR (|) operator like in C++. Before Java 5, people used constant integers on interfaces as a poor man's enumeration that also supported this. And yes, Java's minimalism is (or was) part of its philosophy. Less can definitely be more, as it prevents complexity and errors. But it seems to me that times may be changing since the advent of Java 5 (and C#). It looks like they'll be introducing closures next, which is normally a good feature, but it makes inner classes somewhat redundant. (Not to mention that it means that existing libraries will then no longer be using the preferred delegation construct.) Just like enums did for the old ints-on-interfaces. What began by copying the major feature differences with C#, may turn out to be a whole new direction for Java. In that sense I am definitely convinced Java was influenced by C#. Likewise, Java's (product) open-sourcing wasn't just the new CEO and the old "Java isn't free enough for Linux" thing, it was also influenced by competition with C# on Mono (which was free enough for Linux). - Chip Zero 17:18, 26 February 2007 (UTC)


 * "What began by copying the major feature differences with C#". I'm not accepting this premise at all—certainly not as a motivation for the changes.  And closures have been discussed since the beginning (even as part of the initial language, and again when inner classes were being added.) —Doug Bell talk 17:30, 26 February 2007 (UTC)


 * I ended up removing the C# "influenced by" statement, mostly on the grounds that the note attached to it offered three cites, none of which were reliable: one was a forum post and another was a personal web page, and neither of the authors seemed to be authoritative. The third cite was to a history of programming languages page whose only related cite for this information was THIS page! Keeping the "influenced by C++" statement without any useful cites didn't seem like the thing to do, given the contraversy around the topic.  SlitherM 00:37, 21 March 2007 (UTC)


 * While I agree we shouldn't cite forum posts, I don't think there's anything wrong with the other two sources. Both were in-depth studies of the subject. The "history" page is referenced in hundreds of web pages and in several scientific publications. And I don't know if you noticed, but the other "influences" don't have any references or explanation. What was the influence of Eiffel for example? And what sources are there for that? I think you're severely exaggerating about the lack of authority of the references. Am I sensing some hostility specific against C#? I'm no fan of Microsoft and their politics either – far from it – but I think it's wrong not to list C#'s influence on Java. That it was influenced by C# doesn't make Java inferior, it just means it's keeping up with the current trends and adapting to the new market conditions. And it did just that by adding "the enhanced for loop, autoboxing, varargs and annotations". They are all features that existed before in C#, and were some of the most notable differences between the two languages. – Chip Zero 21:53, 23 March 2007 (UTC)


 * Thanks for pointing out that the influence of Eiffel was lacking a citation -- I just added one. As for the influence of C#, perhaps it would be best if we try not to sense hostility in each other?  My position is just that the cites given don't seem to me to be reliable, and I don't see any reason to think that there should be an influence.  Tackling the first point first: The "history" page that is cited, if you look at its edit history, doesn't give any attribution and, as I said before, the only reference it gives that relates to C#'s influence is THIS page, which raises the question of whether that page only claims that C# is an influence because this one does!  The other cite is to a unrefereed talk by Barry Cornelius, in which he explicitly says "In my opinion, it is C# that has caused these radical changes to the Java language" (emphasis added).  Therefore, I think it cannot be taken as reliable either.


 * As to my second point, I don't see any reason to think C# should have been an influence. JSR 201 added these features, but doesn't claim any influence. The only two non-simple features it added were enums and autoboxing. Java's enums are VERY different from C#'s, and boxing and unboxing are old ideas that have been around well before Java.  For instance, Xavier Leroy's 1992 article .  So, without any citations in favour of an influence, why assume that there is one?  SlitherM 01:49, 24 March 2007 (UTC)


 * I'm not sure where you see a reference to this article, but it seems that the "history" page added this influence in May 2005, while this page added it in November 2006. You're right about enums, we actually discussed this (see above), and removed it from the list of features. As for autoboxing, yes, "boxing" and "unboxing" are no new concepts. What Xavier Leroy describes is a way to use recursive unboxed memory allocation as an optimization for a language that normally uses fully boxed types. The novel thing about what C# and Java did is adding (non-recursive) boxing and unboxing to a language with a type system that already supports both boxed and unboxed types, thereby introducing polymorphism for the primitives. Furthermore they still require explicit use of an object type (boxed type) in methods or data structures to make use of this. So I don't think it's really the same thing, although C# autoboxing probably had a basis in this or related papers. Anyway, try a Google search for autoboxing C# java. You'll find many articles that have made the observation that Java introduced autoboxing and other features that were present in C# before. Java 5 simply added most of the major features that introduced were in C# but were not yet in Java, and implemented them in the same way, with only some superficial differences. This includes annotations, which I would definitely consider "non-simple". Just that the JSR (which didn't make the design discussion public) didn't mention the influence doesn't mean there isn't one; that's why we have to look at external observations. Anyway, good job on the Eiffel citation. (Although I'm still not exactly sure what aspects were influenced by Eiffel, but that's probably just me.) – Chip Zero 11:56, 26 March 2007 (UTC)


 * I'm not even sure why we even put Influenced by here in the first place, clearly intense competition for the developer's hearts and minds influenced the JCP committee to add some features found in other languages but were not there before Java 5 (Note: Sun no longer calls it 1.5 but Java 5). Certainly C# wasn't the original language to introduce generics.  If you can name at least one ORIGINAL feature in the C# language that is also found in Java as of version 6 then I will agree with you, otherwise lets just delete the whole thing as the PROGRAMMERS and DEVELOPER community ultimately influence a certain language. Daimengrui 08:22, 15 November 2007 (UTC)


 * All languages are influenced by previous languages - after all, Java's memory management is in response to noted issues with pointers as seen in C++.

I'd argue against C# influencing Java. If you look at things like Generics, the JSR was in progress one hell of a long time. Can research a few others, but the number of ideas from C# introduced into Java, if there are some, is negligable with regards to claiming C# influenced Java.

Minkythecat (talk) 13:49, 11 March 2008 (UTC)


 * Influenced by J# - is somebody seriously having a laugh / trolling? A Microsoft language intended to replace java influenced Java? Minkythecat (talk) 13:58, 11 March 2008 (UTC)

Compilation
The first paragraph of the article says that "Java is an object-oriented programming language developed by Sun Microsystems in the early 1990s. Java applications are compiled to bytecode, which at runtime is either interpreted or compiled to native machine code for execution."

This makes it seem that java can run by either:


 * 1) Interpreting bytecode at run time
 * 2) Compiling bytecode to native code at run time

Thus leaving out the possibility of compiling to native code ahead of time. Jorge Peixoto 02:57, 9 March 2007 (UTC)


 * To the best of my knowledge, an implementation directly compiling from .java files to native machine code would not be Java (since bytecode spec is also part of the standard). Otherwise, the sentence you cited does not say anything about whether bytecode should be compiled to native code at runtime or not, so ahead-of-time compilers, such as Excelsior JET, are seemingly covered by it. -- int19h 15:39, 9 March 2007 (UTC)


 * Actually, the Java Language Specification is a completely separate document than the Java Virtual Machine Specification. The language spec describes how the language behaves, and says nothing about how the JVM works, or how it should be compiled other than that the compiled code should work correctly.  Therefore, it would be entirely legal to compile Java code to native code. I agree with Jorge Peixoto that the first paragraph is misleading. SlitherM 00:20, 21 March 2007 (UTC)


 * I've considered changing that statement myself. The fact is that the language and VM specs were intentionally kept at arms-length so as to allow the widest possible latitude for environments that run the Java language.  There is nothing in the language spec requiring compilation to bytecode, AFAIK, and in fact, there have been a number of implementations, esp. early when performance was a bigger issue than now, that compiled directly to native code.  So I would support at least a qualification to the statement.  The statement also doesn't allow for the execution of the bytecode natively—there were some early stack-based Java processors that executed the bytecode directly.  My recommendation would be:
 * "Java is an object-oriented programming language developed by Sun Microsystems in the early 1990s. Java applications are typically compiled to bytecode. At runtime, bytecode is usually either interpreted or compiled to native machine code for execution, although direct hardware execution of bytecode by a Java processor is also possible."
 * —Doug Bell talk 05:34, 21 March 2007 (UTC)


 * Sounds good. You should probably add something like "or native compilation using GCJ is also possible.". – Chip Zero 21:56, 23 March 2007 (UTC)


 * OK, I changed the wording. —Doug Bell talk 22:05, 23 March 2007 (UTC)
 * Great, sounds much better now. – Chip Zero 11:57, 26 March 2007 (UTC)

Too heavily criticized
This is not a neutrally or fairly written article by any stretch. There is entirely too much emphasis on criticism. Since there is an entirely separate article devoted to criticism, then there should be no mention of it here. —The preceding unsigned comment was added by 65.118.4.1 (talk) 16:28, 1 May 2007 (UTC). It seems like every article on wikipedia has a criticism section. But I think that "no mention of it here" would be stupid, because it's an extension of the article. It'd be like no mention of a list of episodes on the TV show that the list of episodes is about. J&#39;onn J&#39;onzz 11:48, 13 June 2007 (UTC)

C# doesn't have a criticism section. And all of the criticisms about Java would apply to C# wouldn't it? I think the either Java should lose its criticism section (since most other languages don't have a criticism section). Or that the Java Criticism aricle should be changed to criticism of Java and C#. —Preceding unsigned comment added by 65.240.128.253 (talk) 17:48, 6 September 2007 (UTC)


 * I agree that C# should be criticized as well (if youw ant to write the article go ahead). However i dont think C# and java criticisms should be combined. While it is true that the two languages are very similar they have distinct differences in both their API and the language itself. For example delegates are unique to C# and java specifically does not include these or any concept of it. So i think the articles should stay separate, despite some overlap. - Debeo Morium: to be morally bound (Talk | Contribs) 20:09, 6 September 2007 (UTC)


 * Maybe C# is not a heavily criticized because the wiki article is just written better for example in the goals section it is explicitly stated that C# is not intended to compete with C and C++, but it is designed to be economically efficient, it won't offend people who program in other languages or have ever had issues with java's performance (these people do exist in large numbers) if the java article was written in this style.
 * "Although C# applications are intended to be economical with regards to memory and processing power requirements, the language is not intended to compete directly on performance and size with C or assembly language."

Dispute with microsoft
"after Sun claimed that the Microsoft implementation did not support the RMI and JNI interfaces and had added platform-specific features of their own"Was Sun's claim true? What platform-specific features? Also, encyclopaedic content must be referenced. Shinobu 20:15, 6 May 2007 (UTC)
 * It is more than a claim, it is the reason why a judgment prevented Microsoft to call their implementation Java. See for example this Yale University case study here. For example Microsoft made Java programs communicate through COM instead of CORBA (COM is tied to Windows). An excerpt from the referenced study: "They decided to omit the class libraries for Remote Method Invocation (RMI) and to disable generation of output for the new version of the Java Native Interface (JNI). A customer could not use RMI to communicate between Java programs on Windows and Unix. Similarly, a C language program written to extend Java would not operate correctly in the Microsoft environment". See also a synthesis of the judgment here: "The court ordered that if Microsoft ships products that include the Java technology, it must change those products within 90 days to address their failure to pass Sun's compatibility test suite". A complete list of all the proceedings (in PDF) is here Hervegirod 21:40, 6 May 2007 (UTC)


 * See also Visual_J%2B%2B . It was a subject of the 1998 DOJ antitrust trial, the 1997 trademark licensing dispute, and then Sun's private 1.6 billion dollar antitrust lawsuit against Microsoft.

This article has quite a linkfarm, I tagged it. See WP:EL for information about this and why I tagged it. Also, see WP:NOT particularly the part about WIkipedia not being a web directory. Aaron Bowen 11:46, 14 June 2007 (UTC)

"Like in C++ and most other object-oriented languages..."
I just wanted to note that in C++, there is very little distinction between user-defined and built-in types: both can be allocated on either the stack or the free store, pointers and references to both can exist, etc. Probably the only difference between them in C++ is that you can't derive a new class from a built-in type. Since this is a basic language philosophy of C++ (I can go find the part about this in The C++ Programming Language if you want), and very different from the object-primitive separation in Java, I think C++ shouldn't be used as an example (as in "Like in C++...") here.

Howto tag
I have removed the howto tag because it is inappropriate. For example the Reflection (computer science) article contains more sophisticated code than the simple Hello world of the formerly tagged section, and one cannot appreciate, much less read, that article without the ability to read code.

It is like attempting to read an article on music theory without including a few bars of music to denote the topic of discussion. It is not inappropriate to have an article on music for those who can read music. By analogy, it is not inappropriate to have a programming language article for those who can read code; if an article needs explanation, one can listen to the music, for a music article. There are entire CD's which discuss Beethoven's Ninth Symphony, for example. One can watch a program animation, or a program visualization, for a code article.

It is unjust to force the content of a code article to another venue entirely, just for the sake of an inappropriate tag. --Ancheta Wis 01:49, 29 July 2007 (UTC)


 * I'm restoring this. WP:OTHERSTUFFEXISTS is not a good argument. And this isn't "a few bars", it's a series of complete stub programs which are mostly completely opaque to people who don't speak the language. Seriously, we need sample code to explain Java applets? Why is that? Example code is a lazy way of expanding an article without really improving it. Chris Cunningham 11:54, 29 July 2007 (UTC)
 * This just came in: iPhone Hello world. It's a canonical way to learn about a language and its platform. Code samples show subtle things about a language that take a lot of text to convey, otherwise. For example, the fact that prolog returns a boolean value at every call, a nit of a detail that you have to know or your code doesn't work. --Ancheta Wis 17:02, 29 July 2007 (UTC)


 * I'm confused. Yes, it is obvious that when writing a tutorial, code examples are very helpful. But this isn't a tutorial. The tag explicitly states that Wikipedia is not here to teach subject matter. That Prolog returns "yes" or "no" to everything is a fundamental part of its design which is essential to understanding how the language works; that's a completely different kettle of fish to whether we need to actually provide sample code for a Java applet to explain what it is. Chris Cunningham 17:57, 29 July 2007 (UTC)


 * I'd agree. Anyone reading this article will be reading for the overview of the Java language - the history, notable events within Java's history et al.  The examples aren't relevant in that context.  If people want to read wiki to learn Java... well, they'd be far better off reading more accurate sources :p

Sun Bias
Can we conclude that anything written about Sun about Java is non-neutral point of view? Such as the FreeTTS article and goals of the system. Specifically as it pertains to performance comparisons. 128.206.82.56 (talk) 21:03, 21 July 2009 (UTC)done
 * About the goals, the citation is clearly presented as a citation from Sun (even up to quoting the sentences), so the citation within this context is neutral IMHO. About FreeTTS, please make remarks in the appropriate article. And also you should add new sections at the end of the page, not in the middle. Hervegirod (talk) 22:39, 23 July 2009 (UTC)
 * see next comment response.


 * Did you read the FreeTTS research paper? It's a fairly classic application-performance-improvement study that simply shows that some Java applications can be made to run faster than some similar C and C++ applications.  It's well backed up with measurements and descriptions of changes.  All in all, a pretty straightforward respectable paper.  Not an "article", or a marketing brochure, and worthy of respect.  RossPatterson (talk) 02:26, 24 July 2009 (UTC)


 * Look I don't know how many times I have to say this, and they didn't mention what priority mode it was in. You can't compare Java in high priority mode to C in normal priority.  This is why this paper and just about everyting coming from Sun is biased, with respect to performance. 128.206.82.56 (talk) 18:48, 24 July 2009 (UTC)done


 * might I also add that the FreeTTS was only tested on Solaris. I mean really Sun not biased about their own product.128.206.82.56 (talk) 19:26, 24 July 2009 (UTC)done
 * If you find reliable sources which say this, I have no problem with that, but for now, your opinion (though respectable in itself) looks to me as WP:OR and thus should not be put in the article. Hervegirod (talk) 21:45, 24 July 2009 (UTC)
 * That is what the article said. Tested on Solaris.  I have no idea if there is a good Solaris compiler.  I know for intel platforms, you can get an icc compiler that is much faster than GCC(maybe 100% to 200%), and there are extensive tests in Windows and Linux that these compilers are indeed faster than GCC.  Of course you can't compare Java compilers to ICC compilers, because ICC doesn't work on Solaris, and Java hasn't been optimized for intel.  NOt to mention being shipped in high priority.  So maybe the statement should be that Sun's Java code is faster than Sun's C code. 128.206.82.56 (talk) 21:53, 24 July 2009 (UTC)done

static / AOT compilation
What is the following sentence meant to say?

AOT could give Java something close to native performance, yet it is still not portable since there are no compiler directives, and all the pointers are indirect with no way to micro manage garbage collection.

This seems like total gibberish to me. The "lack of compiler directives" is unclear as to its meaning, and I can't imagine what the author of this phrase meant to imply with regards to being 'not portable'. Also, the text about 'pointers are indirect with no way to micro manage garbage collection' seems to have nothing to do with either portability or performance.

I'd suggest this entire (long) sentence be struck. Jonabbey (talk) 22:00, 15 July 2009 (UTC)

Seeing that this talk page isn't currently very active, I went ahead and struck the sentence. Jonabbey (talk) 22:09, 15 July 2009 (UTC)


 * Sorry I haven't watched it for a while so I undid it. Compiler directives are how programmers make a program compile on different platforms, that have incompatible operating systems, if you have ever tried to use jni you know what I mean.  Garbage collection accounts for a majority of the over head in the language, and objects/pointers or indirection are what slow down programs again if you have ever used jni you know what I mean. 128.206.82.56 (talk) 15:08, 16 July 2009 (UTC)done


 * I understand what compiler directives are.. I've been programming for 30 years, in Java for 14. What I meant was, what does it matter whether there are compiler directives, when the Java code is itself written to an abstract machine?  It can be left to the AOT compiler to compile and optimize the code for a specific architecture.  Such compilers can of course feature whatever compiler directives they like.  This doesn't make the code less portable.  As to garbage collection, modern JVMs actually achieve superb memory management performance.. easily superior to a naive malloc/free implementation for many purposes.  Other things you cite such as object orientation, virtual methods, the ubiquitous use of immutable Strings (thereby necessitating lots of intermediate String object construction for _many_ common operations) do have performance implications.  Bounds and exception checking can do also.  But that's what makes Java code as reliable as it is. Jonabbey (talk) 22:47, 16 July 2009 (UTC)
 * Garabage still has to check for dead objects. This an inherent problem in the language it self and has nothing to do with the implementation.   IE AOT compilation won't do anything to improve this. The lack of compiler directives are again a fault of the language.  If I can't sysexec or load a library then Java is useless because there is so much really good code written cross platform style out there that I will never be able to use in Java.  JNI can do it, but again it has no compiler directives so no cross platform for that code... Lame.  Slow torpid boring java, like stale coffee.  Besides with Chromium, you can run C++ in a sandboxed environment so there is no benefit to Java anymore, except the language was bought by Oracle and is currently under anti-trust review. 128.206.82.56 (talk) 14:01, 17 July 2009 (UTC)done
 * You obviously have extremely strong feelings about this. You also seem to be confusing Java (programming language) with Java (software platform).  You also are completely disregarding everything about Java other than its performance and ability to use C/C++ libraries.  If that's your primary concern, why not stick to C/C++?  I'm sure those wiki pages could benefit from your expertise. Jonabbey (talk) 15:52, 17 July 2009 (UTC)
 * Because developers seldom make choices about the adoption of software technologies, and I wouldn't want some potential CEO to be misinformed with all this nonsense about cross platform and similar performance. But mostly I wouldn't want java developers to have the same pay scale as C/C++ programmers for making obviously infereior programs.  128.206.82.56 (talk) 20:36, 17 July 2009 (UTC)done

 * I'm trying to cut down on the unnecessary geekishness just now. Once the article is shorter and has more focus I'll try to add a section about Java's applications and how its use has affected the computing world. Chris Cunningham 17:45, 30 July 2007 (UTC)

I appreciate the idea of adding a section concerning use of Java, but I'm concerned about the general difficulty of the main article for a non-computer science reader. The point of Wikipedia, it seems to me, is to create articles for common folks who have, let's say, graduated high school. This article is opaque to me and I have a liberal arts MA. The article assumes far too much about my prior knowledge. Trying to understand the definitions doesn't work because the linked terms simply hyper me over to other, similarly difficult articles. The article (and many others) would benefit from a knowledgeable person adding simple metaphors. For example, is a library a toolbox and each class is a tool? Also, defining each term separately, rather than tossing six terms in a sentence would be great. Thanks. BeholdMan (talk) 05:35, 7 February 2008 (UTC)

Essentially Java was a marketing scheme by Sun microsystems to get businesses using their stuff. They developed a poorly thought out language, and sold the hell out of it to businsesses as an "enterprise"[1] "solution". When it was first released there were claims made that java code could be written by less skilled programmers (You can hire stupid people now!), similar to the Cobol programming language in the 60's and 70's. This of course was a disaster, resulting in poorly designed software written by people without the fundamental understanding of the problems they were trying to solve. In the end java exists entirely to soak up IT budgets and keep IT consultants' families fed. Microsoft's .NET technologies were Microsoft's attempt to counter Java. All the same criticisms apply to it. Except that it's 10 years late to the party.

"enterprise" of course means it's very expensive, slow to work in and you'll need to hire lots of consultants. And at the end of it your competition will still run rings around your using something else. —Preceding unsigned comment added by 24.68.49.1 (talk) 05:10, 23 April 2009 (UTC)

Importance rating
How come that this article gets only a "Mid" importance rating, when APL (sic!) gets a "High" rating?? I can only laugh on that.

Or it's not the most important enterprise software development platform today. It really depends on who you're talking to. You might make an argument for most /popular/ but if you're going to do that, include some statistics, thanks.137.48.130.200 17:56, 8 October 2007 (UTC)
 * @80: Even C++ has mid-importance in the Computer Science WikiProject. For WikiProject Programming languages evaluation, this article should have high importance; in terms of Computer Science; I'm not so sure. If you think that APL should also be rated as mid-importance, or that all major programming languages should be high-importance, please effect that change (ideally with discussion first here). Evaluation of importance is specific to a WikiProject's need to prioritize improving certain articles, and is a tool, not a description to help or hurt its subject's image. Grace notes T § 06:46, 14 October 2007 (UTC)


 * I think the importance is in terms of a need for improvment, not a relative ranking of topics merit, I assure you java doesn't deserve any more merit than some other language. The C++ article reads fairly informatively and concisely with little misinformation, therefore doesn't need improvment, unlike this article which reads like a cross between a marketing brochure and a java text book for beginning java students, with out all of the flash of the former or cohesiveness of the latter might I add. 128.206.82.56 (talk) 21:16, 9 June 2009 (UTC)done

Java update
Every time I start up my laptop, I get an annoying reminder that there is a Java update ready to download and install. A few minutes ago, I finally gave in and installed it. The problem is, I don't know what the hell Java is, and this article doesn't really help. The installation set-up only said that the download will make my "Internet experience richer."

 * What you have is a Java Plugin that runs Java applets in your browser, that are similar to Flash and ActiveX plugins. Those programs are used to create better interactive pages and normally the user will be unaware of it existence if everything is right and that is the reason for the constant updates. The other plataforms also have similar updates, but normally without notifying the user. This aspect of the Java technology is, however, a small portion (and quite francly one part in disuse) and this article had to deal with the entire aspect of the technology, making a good part of this technical jargon and doesnt making much sense to ppl outside of the software development market. Alvaroludolf 12:48, 25 October 2007 (UTC)


 * Not that this is a general discussion forum or anything, but for what it's worth the relevant article is Java (Sun) and the "technical jargon" here is no worse than that on random chemistry articles. For some reason, people seem to assume that computer science shouldn't be treated in a scientific manner on Wikipedia even though other sciences are. Chris Cunningham 12:58, 25 October 2007 (UTC)


 * I'm sorry you couldn't get the answers you needed. I agree the article is too techie. Maybe a techie will improve this. I'll try to help. In plain English, Java is a software technology that lets Web pages run programs on your computer, if you choose to allow them to. For example, if you want to play Yahoo Text Twist, you go to http://get.games.yahoo.com/proddesc?gamekey=texttwist and click on "Play Web Game (free)". You will see the Java symbol and a progress bar as the game loads. The Java technology is what runs the game in your browser.


 * Java is considered much safer than its competitor, Microsoft's ActiveX technology. The United States Computer Emergency Readiness Team, a division of the US Department of Homeland Security, has noted numerous critical security flaws in ActiveX, including in MySpace and Facebook, which could allow an attacker to take control of your computer. They "are currently unaware of a practical solution to this problem", and therefore recommend that you disable all ActiveX capability in Internet Explorer. They give instructions to do so, but an easier solution is to use a browser like Mozilla Firefox that inherently does not support (run) ActiveX programs. You will still need Internet Explorer and its ActiveX to get the latest Windows security fixes from the Microsoft Update page. These are issued the second Tuesday of each month and you need them for your safety. Other than that, Internet Explorer and ActiveX are unsafe and should not be used.


 * The automatic updating of your Java can be controlled if you like. Going back to playing the Text Twist game, you will see a Java icon in at the bottom of your screen. I think it's supposed to represent a cup of coffee ("Java"), but it's two blue lines with a red thing above. The large version is shown in this article. If in doubt, hover the mouse pointer over it and it will say "Java (TM) Platform, Standard Edition". Right-click this icon, then click "Open Control Panel". Click the "Update" tab. If you wish, you can uncheck "Check for updates automatically". However, these updates too may be for security reasons, so it's probably better to continue to allow them and install them.


 * 65.43.178.200 has made the common error of confusing Java and Javascript. As Cynic783 points out, these are two completely different technologies. The reasons for this unfortunate confusion can be found in the Javascript article if you are interested. The important thing is that Javascript is also dangerous, the source of many current security issues for all Web browsers. The aforementioned US-CERT recommends adding the NoScript program to your Firefox browser. With this free addition, you can disable all Javascripting by default. When a trusted site (your bank) wants to run a Javascript, you can click and verify that it comes from the trusted source and allow it permanently (it won't have to ask you again). When a site (like Yahoo email) tries to run scripts from multiple sources, you can allow the script from Yahoo while forbidding the script from advertising.com or DoubleClick.net. This ability to discriminate among scripts coming from the same Web page is not available in Internet Explorer.


 * I'm not connected with Sun Microsystems, Mozilla/Firefox, or NoScript. I'm just another dumb user trying to stay safe in a shark-infested Internet. All of the above is free software and the POV is that of the US Dept. of Homeland Security. I agree that these articles should be more accessible to average users.

 * The programming language is called Java. JavaScript is a scripting language used mainly for web page functionality.  Java is not JavaScript - JavaScript was confusingly named to play off of the Java name.

I've not checked, but as the two are distinct entities, JavaScript should have it's own page. Minkythecat (talk) 13:56, 11 March 2008 (UTC)

I would like to say something: JavaScript is very loosely based off of the Java language, however, it is its own separate entity and programming language. So, in regards to the argument of should this article be Java or JavaScript, it should be Java because JavaScript has its own language (similar to java, but not in its functions and their execution). --TrekCaptainUSA (talk) 14:38, 20 October 2008 (UTC)
 * No, Javascript is very loosely based off of C and C++, while Java is much closer to C/C++. Neither has inherited anything from the other.

 * It explains that Java is a programming language. Programming languages have a great deal of uses, only one of which is writing web pages. There's no definitive way to tell what language a web page is "written in"; it can be manually created by an author with HTML, or it can be generated by a web server which runs programs written in Java or PHP (amongst others). There's only so much an article lead can be simplified when it deals with a complicated subject; a panda can be explained as a big bear-like thing which lives in China, because "bear" and "China" are pretty familiar concepts to people.

I think the "Swing application" example need some fixes:
 * WindowConstants.EXIT_ON_CLOSE -> EXIT_ON_CLOSE
 * setLayout(new BorderLayout); can be removed
 * new Hello.setVisible(true); should be launched on EDT using SwingUtilities.invokeLater
 * my take on your proposal:


 * WindowConstants.EXIT_ON_CLOSE : You are technically right, but I think it is clearer to see WindowConstants.EXIT_ON_CLOSE here (it's then clear that you use a particular swing constant, not some magic thing coming with JFrame)
 * setLayout(new BorderLayout): on one hand it adds some unneeded complexity to a Hello World program (what is a BorderLayout, etc..), but on the other hand approx. every Swing program has to use layout managers at one point, so I don't know what's better
 * SwingUtilities.invokeLater: I think your proposal would add unnecessary complexity. There is no no action here, so I don't think it is a good thing to add this (we should keep a Hello World program simple, and it is not needed here IMHO). Hervegirod (talk) 21:30, 29 October 2008 (UTC)

Productivity
This section should be removed: It is clearly POV, and using a very old reference (Java 1.2.1, benchmarks seem to be from 1999) whose conclusion are also very questionable, even at the time. Some quotes:
 * In terms of run time and memory consumption, (scripting languages) often turn out better than Java and not much worse than C or C++. On the contrary, the last Computer language Shootout shows a factor 13 between Java and Python or Perl, 29 between Java and Tcl, 15 between Java and PHP, etc... I don't present the figures with C / C++ because it would be ridiculous,
 * The article deal with some very specific types of programs (string manipulation and search in a dictionary). The section makes a generalization that is not in the original source conclusions.
 * It is an interesting observation that despite the existence of hash table implementations in both the Java and the C++ class libraries none of the non-script programmers used them (but rather implemented a tree solution by hand) : I never saw anyone redesigning by hand collections implementations in Java since a lot of years, except for very specific cases (for example Hashtables with an exceptionally huge number of key-value pairs)
 * In contrast, essentially all of the non-script programmers chose either of the following solutions. In the simple case, they simply store the whole dictionary in an array : No real Java programmer would do that. I bet that they asked C programmers with no experience in other languages do the programming in Java (which I may understand, there were less Java programmers in 1997 !!)
 * The Java work times appear to be a bit pessimistic, probably due to the lower language experience of the 1997/1998 Java programmers. : sic !!!
 * Even in the group-aggregated view with its much larger groups, the difference between C/C++ and scripts is not significant, only Java is less productive than scripts. Hervegirod (talk) 22:25, 18 March 2008 (UTC)

 * You already quoted this in the article, but your example is not significant. You used the specific Java -Xint results of the shootout. -Xint is purely interpreted Java, meaning no JIT, meaning performance of the 90's era for Java. On the contrary, it shows Java performance has improved a lot over time. But I don't think this is even worth mentioning, because comparing nowadays Java using Hotspot / JIT with interpreted Java is comparing apples to rice noodles (oranges are closer) ;) Hervegirod (talk) 21:57, 30 July 2009 (UTC)

The article claims: Dynamic recompilation can achieve optimizations superior to static compilation because the dynamic compiler can base optimizations on knowledge about the runtime environment and the set of loaded classes, and can identify the hot spots (parts of the program, often inner loops, that take up the most execution time)

This is bogus. You can profile a static compiled programm and give this input to your compiler to recompile your programm with this information. —Preceding unsigned comment added by 87.123.216.181 (talk) 23:11, 14 May 2008 (UTC)

It looks to me that the Criticism section of this article is written in a very defensive tone.

 * I see this continuously with Java, a theoretical concept with large gaps between the theory and practise. This article conveniently forked the conversation Java language and theory and Java JRE or impelementation.  Ultimately I have only ever used one or some online simple applets, and a java student web protal, which has been replaced, so in the course of my computer experience java plays a very small role, and I believe this to be the case with most computer users experiences.  Yet Java is very extensively taught at most universities to undergraduate business students.  The language is continuously changed by the business sector, and is not standardized, so arguing against any one point and there are very many, is probably useless as is java.
 * Too easy for beginners and too difficult for professionals, I suggest this article "Keep It Simple!"

Abstract Syntax
Since many languages can be compiled to a Java Virtual Machine. The operational definition in the last sentence of the first paragraph, needs to be rephrased. 1) Many languages Ada, C, C++ can be compiled to run on the JVM. 2)Java can be compiled directly to machine code.

Furthermore for the naive reader, Virtual Machine may be better discussed elsewhere in the article, since to understand the first paragraph, one would already have to be familiar with the Virtual Machine. —Preceding unsigned comment added by 128.206.82.41 (talk) 19:52, 27 August 2008 (UTC)


 * Yes, it's true that many language may run on the JVM, but that's not relevant to the lead section of the Java article. It's certainly appropriate to the JVM article, and indeed, it is mentioned in the lead there.


 * I'm afraid that that would make this article NPOV.


 * I guess it's also true that Java may be compiled to machine code, but this isn't common practice, not by a long stretch. The lead describes compilation to JVM bytecode as "typical", which I think is all that needs to be said at that point, as the lead is supposed to be a synopsis, not an enumeration of all possibilities.


 * NPOV?


 * The JVM is described at the JVM article, which is linked in the lead. An in-depth discussion isn't appropriate for this article, because it's not a part of the language.  However, you're right, perhaps a brief summary of what a JVM is may help set the scene a little better.  Oli Filth(talk 19:59, 27 August 2008 (UTC)


 * NPOV?


 * If it is not possible for the sake of brevity to enumerate all the problems with a statement, then it is better not to say it, IE that sentence should be removed because there are problems with its validity. Is it a definition wiki of Java for java programmers or a wiki of java for the rest of us?  —Preceding unsigned comment added by 128.206.82.41 (talk • contribs) 21:18, 27 August 2008


 * I'm not sure you necessarily understand what WP:NPOV is about. It is not about mentioning things that are irrelevant (e.g. the fact that Ada compiles to JVM is irrelevant to an article about the Java programming language).  It is also not about providing equal weight that are overwhelmingly less common that the norm (e.g. compiling Java to machine code), especially in the article lead; see WP:UNDUE and the like.


 * The sentence as it stands is completely valid, as it is completely true, and doesn't purport to be a "definition". I see no reason to remove it. Oli Filth(talk 20:27, 27 August 2008 (UTC)


 * Are you trying to wiki Java or wiki wiki lets talk about relevance and NPOV. I said that if you can't enumerate everything that is wrong with a statement then you better not say it.  Java is not the end all be all language... Java is not the definition of language, Java is a subset of Computer Languages, and as are most Computer Languages architecture independent so is Java.  This concept is very relevant to this article.  If Java is not a computer language what is this article about anyway?

Compiled vs. interpreted
Deary me, are we really having this discussion?

Typically, Java source code (i.e. the stuff you write your application in) is compiled to Java bytecode. The bytecode is then interpreted by the JVM. This is obvious from the fact that one has to run javac (the "Java compiler") on the source code before you obtain something that's executable by the JVM. To say otherwise is incorrect, no matter what that early reference says (look, I can find a reference that disagrees with yours: !), and contradicts the article later on (Java (programming language)).

Automatic memory management
I think this section can be largely removed/rewritten, the second paragraph is useful but the majority of the rest is general information on garbage collecting (i.e. not java specific) and/or has too much comparison with c/c++. Superfly Jon (talk) 10:08, 10 September 2008 (UTC)

Primary goals v cite
The five primary goals listed in the article don't obviously match the 5 goals listed in the citation given? Regards, Ben Aveling 04:45, 10 September 2008 (UTC)


 * I agree that it doesn't seem to match exactly. Here are the paragraph headings from the article:


 * Simple, Object Oriented, and Familiar
 * Robust and Secure
 * Architecture Neutral and Portable
 * High Performance
 * Interpreted, Threaded, and Dynamic


 * The first 3 roughly match points 5, 4 and 2. Point 1 is also covered in the first part and point 3 seems wrong.  None of the points mention high performance.Superfly Jon (talk) 10:07, 10 September 2008 (UTC)


 * These are all goals that C and C++ have already attained, and are all short falls of java except perhaps interpreted.
 * Using goals as facts is a fallacy, garbage collection is not DYNAMIC! done128.206.82.41 (talk) 18:56, 11 September 2008 (UTC)
 * Also note that no where is Java designed to work well with other languages.


 * C and Java are simple, C++ is not. Neither C nor C++ is really OO.  Java basically is OO, pretty much. C is familiar, C++ gets pretty weird in places.  Java is pretty familiar, though it seems to get a bit weirder with each new release - arguably, as it tries to be more like C++.
 * Java too easy for beginners too difficult for professionals.
 * No language that allows ints and pointers to be used interchangeably is robust or secure (but you can still write robust and secure programs in them).
 * I thought you meant secure from hackers. But really we meant secure from poor programming.  Why is it that all the Java programs require relaxing of my security standards?
 * C and C++ are reasonably portable, but not completely. For example, resolving a null pointer isn't fatal on some platforms.  C/C++ are certainly are much less architecture neutral than Java - they need to be recompiled for each new platform.  For a large program, that's not a trivial exercise, though it's probably better than it used to be.
 * bottom line is if C and C++ is portable Java isn't portable, thank you JRE. I think you are confusing portability with cross platform.  Java doesn't have compiler directives, so you can't port it, or you can port it but you have to maintain two different version of said program, which is definitely not portable.
 * Yes.  C beats Java hands down.  C++ also, unless your programmer goes too deep into the box of magic tricks.
 * I can link C libraries to my C++ code so fast you can't imagine, so there is always a way to get it done fast, the line between C and C++ is faint, unlike Java where it is a memory management nightmare, every object has to be wrapped and unwrapped to get C to work with Java, and then you still have issues of in Linux its a .so file and Windows its a DLL, and there doesn't seem to be a way to tell Java that hey you need to load a different library ... see portability point above.
 * Interpreted has pluses and minuses. Java threading is out of the box.  Dynamic, I'll let you decide.
 * Java still can't decide interpretted or compiled, it disagrees with the lead of the article.

 * Java is not a nice program in the sense that it ships in preemptive task mode. done 128.206.82.41 (talk) 20:47, 12 September 2008 (UTC)


 * I agree completely with user:thumperward. It is completely out of the subject. It is like saying "Red is not nice because it is not White". Hervegirod (talk) 13:52, 13 September 2008 (UTC)


 * Actually preemptive task switching is relevant to the discussion of measuring performance of a language. A program can gain apparent performance by starving other processes of system resources.  So comparing a java program to a C program is not accurate, as Java may be receiving more system resources, and even causing lowlevel IO to appear faster since java doesnt wait.  Preemptive task switching also has the negative side effect of causing the entire system to appear to thrash, when in fact it is one poorly programmed Java program.  Other programs that are guilty of this are MySQL.  In gerenal programs that ship in this mode or use this behavioural marketing tactic are considered "Not Nice". done 69.29.68.204 (talk) 14:42, 13 September 2008 (UTC)


 * Preemptive task switching is at the basis of all modern Operating Systems, in whatever language they are programmed. You may think its cool to throw your own personal war using alternate IPs, but it's not. You should stop this now. Hervegirod (talk) 16:23, 13 September 2008 (UTC)


 * Preemptive task switching is good for OS's, and bad for third party web applets written in languages like Java. I see the point that Java ships what equates to an operating system for the JVM(add a couple gigabytes per version might I add), however there is still no way to run Java programs at different priorities within the context of the JVM the scheduler just isn't there.  It is also true that this is a cross platform issue in that java is not nice in all operating systems, and OS programmers have had to make explicit attempts to keep java from not only using high priority scheduling for all of its threads, but also locking other resources.  I also believe attempts to obscure such issues to be bad faith evangelism, that happens to effect all processes not just java.  Sorry about the IP, maybe if my service provider didn't charge extra for a static IP, I wouldn't have to worry about it.  69.29.68.204 (talk) 16:22, 14 September 2008 (UTC) done


 * As for the dynamic IP, it would be much better to create an account, the actual state of your contributions appear as dubious, even if they are not.


 * A weakness in wiki or a strength in java, I don't understand what you are talking about.


 * BTW it is possible to assign priorities to Java threads (see here).


 * Priorities to threads not to programs. IE there is no way to set an entire java program at any other prioity compared to other java programs, (can you imagine running more than one java program simultaneously?).


 * If you don't assign a priority to a Thread, it has by default a normal priority (not the highest as you wrote).


 * This is for the thread priority. The Java JRE still runs at high priority in the OS kernel as was standardly shipped, which is by definintion Not Nice, just like if I were to run all my java threads in high priority... Not Nice.


 * Yes but the Java Freezing behavior for Applets is not coming from the Threading behavior of the JVM, but to the fact that the Applet code must be downloaded prior to execution, and also because of the initialization of the virtual machine (on my PC PDF documents take more time to open than Java applets, I think more or less for the same reasons). If you find reliable sources saying the contrary, I have no problem with that, but for now it looks like POV to me. Hervegirod (talk) 17:17, 14 September 2008 (UTC)


 * What java freezes my computer no way dude, do the marketroids let you say that? All I am saying is that it would take a little longer for java to load, but it wouldn't lock my computer and cause my system to drag if it weren't shipped in high priority mode. done 128.206.82.41 (talk) 14:28, 15 September 2008 (UTC)

AOT

Poor or Irrelevant Examples??
The section  Examples is marked but nobody tells us why, on this talk page. That's poor templating! Now are the examples poor? IMHO: Maybe – I got warnings when compiling them with gcj, but they executed. They're IMHO not so poor, but needs improvement. Are the examples irrelevant? IMHO: somewhat – they happened to be exactly what I needed, just now, thank You very much someone, but they belong to Java applet and Java servlet, technically – they don't explain the language Java, which IMHO is what the article should treat. Have opinions! (Or if hungry: onions). Said: Rursus (☻) 13:27, 20 October 2008 (UTC)


 * i agree (mostly), when reading the examples they where just what i wanted so i'm going to delete the tag. but i'm slightly confused by your comments cos the applet/servlet stuff is under a different section, ie Special Classes which seems fine to me. tho i'd probably like to see those examples in the Java applet and Java servlet pages too. cheers.

User spreading unsourced POV views on the article
An unregistererd user signing doneon many of his contributions (he is often using Special:Contributions/128.206.82.56 IP) is spreading FUD on Java performance, and repeatedly revert other people edits in order to give his own personal view. He is obviously convinced that Java is very slow compared to C, and has started to modify this article according to his own views. He has recently edited (and already reverted) the Performance optimizations paragraph with the sentence: "however there are cases where Java is more than 30 times slower than C". The problem is that the benchmark he quote compares GNU GCC with Java with the -Xint flag, so with purely interpreted Java. When I reverted this with this explanation, he replied on the Talk page:'''You obviously didn't read the reference. There is also a server mode. This article reports best case scenario, there are also worst case scenarios''' (which he did not provide of course).

The "evangelism" stuff is inappropriate to an article describing a program language; if Sun/Oracle is engaged in Java "evangelism" (and, as Java is a part of their product strategy, they probably are to the extent of "advertising" it), anything notable about this activity is more apropos to Sun/Oracle company pages than to a general description of a language that has also been implemented by independent FOSS projects.

Comparison of ABAP and Java
This article was proposed for deletion on the grounds of unfixable original research. I deprodded as it seemed to me that a comparison between the two was reasonable, but I don't know enough about computer programming to properly assess and fix the article. Any assessments of it and editing would be welcome. Fences &amp;  Windows  16:05, 8 August 2009 (UTC)
 * The problem for me is: these two languages are so different that is it really possible to compare them effectively ? And further: it seems that there is an interest in comparing the two languages because I see that one of the links is a wiki just about this comparison. What are the use cases that make such a comparison interesting, or even switching from one language to another interesting (it is obvious for general purpose languages) ? Perhaps the comparison would be really a useful article if it shows that some of the use cases for the two languages overlap (i.e., for ABAP, because I think hat Java is a more general purpose language) ? I'm not trying to say that one language is better than the other, I'm just asking (even myself) questions that pop in my mind whose answers could improve this comparison article IMHO. Hervegirod (talk) 16:20, 8 August 2009 (UTC)
 * The idea that java is more general is a farce promoted by naive programmers and Sun executives. Its not more general, becuase it lacks several key features that prevent this.

These are defects in the language itself, and not implmentaion specific, IE a mature language needs to be able to adapted to the environment it is run in to ensure similar behavious, java operates under the assumption that all environements should be the same. There are reasons why some DLL's and SO's operate differently and it is foolish to try claim that they are the same or make them be the same. The one technical reason for using java being that it can be run under a restricted security model is no longer an advantage, since any language can be run in a sandbox with modern operating systems. —Preceding unsigned comment added by 128.206.82.56 (talk) 16:32, 10 August 2009 (UTC)

 * 2) Java lacks compiler directives so it isn't actually cross platform.
 * 3) Java lacks the ability to do memory allocation, see why java is slower.
 * this is blatant WP:OR and WP:POV. ABAP is a language for programming SAP Web application Server, it seems a little (to say the least) more restricted than Java.

Stuff removed from Boolean data type article
The following section was removed from the article Boolean data type: begin removed text

In the Java programming language, Boolean variables are represented by the primitive type. The Java Virtual Machine (JVM) abstracts away from the actual representation in memory, so JVM writers can represent Boolean values in whatever manner is convenient (for example, one byte, or one word).

The Java Language Specification does not permit any explicit or implicit casts to or from. Thus, it requires the compiler to reject this code:

because the integer variable  cannot be cast to a Boolean type, and the   statement requires a   condition.

In Java,  values (like other primitive types) can be appended to Strings. This feature provides a default visual representation of a Boolean value ( is displayed as "true" and   as "false").

Another way to use Boolean values is to set a variable type as a Boolean type. This can be done in the following:

Criticism
Criticism of Java used to be a standalone article (albeit a very stub-like one). With as much Java-bashing as goes on on the Internet, are there really so few legitimate problems with it that this article needs none? I don't see any criticism at all, aside from the description of the garbage collector potentially causing a pause in execution.
 * Everything has some flaws and thus criticism. In my most humble opinion, some java weenies removed the criticism. I'm not saying we should post stuff like "Java sucks because" and other *bashing*, but we should focus on shortcomings, perceived or otherwise. One legitimate criticism I have is lack of Multiple-Inheritance. If you zip over to the equivalent C++ article, you'll note that this specific feature is a Criticism of that language. Really, it all depends on who you are, what you're doing and why you choose a language. Another criticism is quite simply it doesn't always live up to its "cross platform" claims, as everybody except Windows seems to be lagging behind a whole version (we'll only examine the "mainline distribution" for this particular argument) while they're off developing a WHOLE NEW version. This in my opinion is also a huge failure in them to uphold a basic tenant that they've built their advertising and advocacy upon. So there you have it, two very legitimate criticisms (without citations mind you) that I have to offer. And let's not turn this into a language-war please, I'm merely stating the FACTS about every language having it's pitfalls - perceived or otherwise. 142.167.13.139 (talk) 17:37, 2 September 2010 (UTC)

Product advertising
The text said "To boost even further the speed performances that can be achieved using the Java language, Systronix made JStik,[29] a microcontroller based on the aJile Systems[30] line of embedded Java processors."

However this is not quite accurate. The text implies that a certain speed is not achievable using Java alone, but that Systronix makes that speed possible. However, such a certain speed is possible using many processors; for example a modern Intel CPU (or even an old CPU) will easily run fast enough to beat Systronics figure of 15M byte codes/sec. —Preceding unsigned comment added by 64.103.25.233 (talk) 04:08, 20 January 2011 (UTC)

Merge Criticism of Java
Back in April, the article Criticism of Java was proposed for merger into this article. However proper protocol wasn't used and no actual real discussion took place that I can find. The merger was then performed, however most of the content was not salvaged in the process (effectively deleted without AfD proposal). For now, I have reverted the redirect on the page to re-propose this merge again. Criticism pages are always difficult monsters on Wikipedia because they attract a lot of bad apples. If it's decided that the content is verifiable and neutral then the page's contents should remain intact, either in its own article or merged into this one. -- Zac  Bowling  (user 16:32, 25 September 2010 (UTC)
 * I think that merging it with this article is a good idea. Sae1962 (talk) 09:49, 7 October 2010 (UTC)

I dont see a criticism section in Ruby or Visual Basic. I think most good software engineers would see Java lightyears ahead of Visual Basic. Anyway the main criticisms of Java are kind of moot anyway, particularly performance : it lists a big Performance heading, and then the first thing it says is that it really isn't an issue anymore. —Preceding unsigned comment added by 213.61.74.55 (talk) 12:30, 11 October 2010 (UTC)
 * There is plenty of criticism of other programming languages. For example, C++#Criticism and .NET Framework#Criticism have dedicated criticism sections.

I think merging the criticism with the article was a very bad idea, as the criticism itself seemed to be hidden away, which is a subtle editorializing in and of itself.

RfC Doubt about Java name
About a week ago I corrected the origin of the Java name. It was said that it was from a list of random words, while the true origin is from the brand of coffee called Java. The former reference was pointing to a suspicious website, that apparently had a copy of an article extracted from a Sun employee's blog, called Jonathan.

I've got a couple of probable hypothesis:
 * the creators of the previous website copied Jonathan's post, published on their site and linked wikipedia in order to increase their pagerank
 * Sun's employee, Jonathan, was said to spread this false history to "change the past" and avoid legal problems with Java coffee brand
 * me and several hundred websites including thefreedictionary.com are wrong about Java deriving its name from coffee's one

In cases like this, how can we find the truth? if all means go through the web, a few linked websites and a good SEO do the job in creating a new truth, because all investigation goes through first results of a google search.. what do you think about this? Atti (talk) 19:28, 2 August 2011 (UTC)
 * What are the sources? - Atti: can you give some sources for the origin of the name (copied from the word for coffee?). I see the article has one source already, but that is just an online dictionary, which is not the best source.  Is there some Java textbook?  Or a history of Sun corp?   Don't worry about "truth" ... see WP:Truth: the key thing is to find reliable sources (WP:RS) that talk about the origin of the word, and incorporate those, even if they indicate multiple origins.  After you find some sources, it will be easy to fix the text in this article to reflect the sources. --Noleander (talk) 21:07, 11 August 2011 (UTC)
 * Here is one source: Machine vision algorithms in Java: techniques and implementation, by Paul F. Whelan, Derek Molloy, p 21.  But it just repeats the coffee story and does not give details from an actual person that was there.   It should be adequate, but it would be better to find a book that actually quotes one of the Java creators. --Noleander (talk) 21:12, 11 August 2011 (UTC)


 * Here is another one - Walter J. Savitch, Java: an introduction to problem solving & programming, Pearson Prentice Hall, 2005, p. 22: "The question of how Java got its name does not have a very interesting answer. The current custom is to name programming languages in pretty much the same way that parents name their children. The creator of the programming language simply chooses any name that sounds good to her or him. The original name of the language was "Oak." Later the creators realized that there already was a computer language named Oak, so they needed another name, and "Java" was chosen. One hears conflicting explanations of the origin of the name "Java." One traditional, perhaps believable, story is that the name was thought of when, after a fruitless meeting in which they tried to come up with a new name, the development team went out for coffee, and the rest is, as they say, history."

Too many examples
I think the article has too many examples and feels to much as a programming textbook. I don't see why there needs to be example code for Applets, Swing GUIs, Servlets with detailed explanations. If you compare it to the C++ or C articles it becomes apparent that the amount of code in the article has to be reduces for readability. What are your opinions on this? --217.209.140.211 (talk) 10:25, 15 January 2012 (UTC)


 * I disagree. I just read this article in full in order to get an understanding of the Java language, and feel that: the source code examples in the Syntax section very much enhance the quality of the article and do not take lengthen the article significantly. I think it is valuable and important to describe the syntax of the language, because syntax is a fundamental component of a programming language. I also think that it would inappropriate to attempt to describe the syntax without examples, and that the examples given are pretty good.


 * Likewise, I think that the examples in the Special Classes section are each justified in that they describe a significant aspect of Java with minimal and tidy source, and concise comments.


 * The line between factual exposition and training is grey, and when the topic is a tool, an example or description of its use constitutes both. The examples in the article enhance the factual description of Java in areas which are fundamental to programming languages, and do not, I believe, make the article overly cumbersome or hard to read. For readers without any knowledge of programming, those sections would be hard to read, but the exposition is well partitioned. Articles describing similarly specialised content in different fields typically adopt a similar style, and I believe this is sensible. (Unsigned comment by 49.129.61.26)


 * I agree there are too many examples (see my comment below that this article is horrible). For this article to be effective, 49.129.61.26, you would have to be a programmer with considerable experience in another language, who happened not to know Java, and who was terribly interested in often trivial differences in programming syntax. That probably constitutes <1% of Wikipedia's general readers. For the other 99% it's either a boring repetition of what they already know, or an incomprehensible barrage of facts they can't understand and probably wouldn't care about if they could.


 * I also disagree that this sterile, unidirectional style is common in Wiki articles on biology, sociology, history, economics, ecology, physics ....

76.102.1.193 (talk) 21:03, 28 May 2012 (UTC)


 * I believe the article is front loaded with examples to prevent criticisms of Java section from expanding, IE the purpose of the extent of the code examples is to take up space so that factually based negative statements cannot be included for example limitations of expression in the Java language preventing portability of code across Java run-time versions either on different platforms or same platforms with different JRE versions, performance of Java implementations, or limitations in the independence of the language specification committee. — Preceding unsigned comment added by 65.125.12.222 (talk) 15:45, 3 August 2012 (UTC)

Simpler object model than C++
This is clearly true, because of no multiple inheritance. What level of RS do you want to back this up? Hcobb (talk) 02:20, 17 October 2012 (UTC)
 * I'm not sure if it's 'clearly true'. Sure Java doesn't have M.I., but there's more to an object model than that.
 * Compared to C it's a no contest - Java has classes for a start, but also inheritance, interfaces, references, different rules for fundamentals and class types, generics, type coercion (auto boxing and unboxing), exceptions and garbage collection.
 * Compared to C++, Java still has interfaces (instead of MI), different rules for fundamentals and class types, generics instead of templates, type coercion (auto boxing and unboxing) and garbage collection.
 * I haven't see any RS that says that 'Java has a simpler object model than C++'. There's plenty that say that Java is simpler, but that's another story.
 * Let me know if you find any decent, clear, RS quotes.
 * peterl (talk) 04:21, 17 October 2012 (UTC)
 * It's best to state facts only, such as "in Java, multiple inheritance is only supported for interfaces" (or a clearer explanation than that blurb that just came off the top of my head). Comparing two programming languages on the basis of "simplicity" is very much a judgement call, and it is difficult to avoid WP:OR. Even where WP:RS have stated such things (and assuming there are no other WP:RS that disagree), trying to work such things into WP articles usually involves a lot of WP:Weasel Words; "some say that Java is simpler...bla bla etc.". -- Nczempin (talk) 06:56, 17 October 2012 (UTC)

Please add the following sentence:

Despite being popular, Java has been criticized for being insecure; some security organizations, including US-CERT  and Sophos, recommend that Java not be enabled by default in web browsers.

to the article lead, the first paragraph then becoming

Java is a general-purpose, concurrent, class-based, object-oriented computer programming language that is specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA), meaning that code that runs on one platform does not need to be recompiled to run on another. Java applications are typically compiled to bytecode (class file) that can run on any Java virtual machine (JVM) regardless of computer architecture. Java is, as of 2012, one of the most popular programming languages in use, particularly for client-server web applications, with a reported 10 million users. Despite being popular, Java has been criticized for being insecure; some security organizations, including US-CERT  and Sophos, recommend that Java not be enabled by default in web browsers. Java was originally developed by James Gosling at Sun Microsystems (which has since merged into Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them.

Emilymab (talk) 15:03, 8 February 2013 (UTC)


 * Oppose. Java has no more of a security issue than most other programming languages - certainly not at a level that belongs in a discussion of the fundamental language. This proposed edit is highly partisan – are we planning a similar edit to Visual Basic for Applications or Windows Scripting Host? There is a security issue certainly. This isn't about the Java language though, it's about the way that the JVM is deliberately made accessible to a browser, and whether the browser JVM's sandbox model is adequately secured. As other languages don't have such a browser-accessible JVM at all, then this issue doesn't arise (not that their language is in any way "more secure"). A very similar issue arises with JavaScript, although that one is even more related to the language, and less about the execution environment. Andy Dingley (talk) 15:23, 8 February 2013 (UTC)

"From an informed point of view" - Java - The General Platform
Over "Ode to Joy" to all (other) nations (from where you are)... That Java has been constructed in reaction to PHP (and other) and that Java highlights some OS issues and of course the democratic issues connected to programming in being "between" the OS and other computing powers and providing separate scripting and programming code where the scripting would be used only rarely... and only because... 95.34.121.134 (talk) 06:57, 19 March 2013 (UTC)

Java and the Cryptation Issues
There has also been a cryptation issue with Java, providing cryptation "as high as you want", fx. 128-bit, being a kind of HTTPS-2, a secondary HTTPS route, being the client-side to the server-side on par with how HTTPS works in the internet world today. That the client-side to the server-side Java delivering HTTPS-services with browser-built-in-compliance, such as embedded "Java-code -> Send information or information capsule" or whatever, transparency preserved by the nature of the transfer of information, withholding the important client-side aspect. This has been discussed on the news-server back then along with the idea of Java itself, but "powers of USA" have had other opinions. This is another side of Java-force, much the same as HTTP and other internet protocols because it has no political agenda, allowing other tasks as well, the programs much like the classics of C and C++. 95.34.149.202 (talk) 10:54, 25 April 2013 (UTC)

Derived from C and C++?
Article states that the “language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them.”

Patrick Naughton said:

“When I left Sun to go to NeXT, I thought Objective-C was the coolest thing since sliced bread, and I hated C++. So, naturally when I stayed to start the (eventually) Java project, Obj-C had a big influence. James Gosling, being much older than I was, he had lots of experience with SmallTalk and Simula68, which we also borrowed from liberally.

The other influence, was that we had lots of friends working at NeXT at the time […] They all joined us in late '92 - early '93 […] I'm pretty sure that Java's 'interface' is a direct rip-off of Obj-C's 'protocol' which was largely designed by these ex-NeXT'ers... Many of those strange primitive wrapper classes, like Integer and Number came from Lee Boynton, one of the early NeXT Obj-C class library guys […]”

It's a known issue that is a threat to Java users then it should be publicly mentioned, to make sure users are aware of this issue then link it to a separate article to help them find a fix, any other related information in case their machine is infected, it's unclear why this would be deleted when it's an important issue, there already reports across the internet about the virus, the reason we don't post links is because of the virus spreading further, the virus seems to be a pop up type that can easily be blocked by using anti-pop up blocker. (I believe this should be mentioned, even if this article only briefly mentions it with a link). I can even provide a random link to prove it's existence here.

Is Java a "C family" programming language?
Please see Categories_for_discussion/Log/2014_October_24. Andy Dingley (talk) 12:18, 24 October 2014 (UTC)

Java influenced by / influenced Python

 * https://stackoverflow.com/questions/7763131/java-for-loop-syntax
 * https://en.wikipedia.org/wiki/Talk:Python_(programming_language)#Influenced_by_Java.3F (Python: 1991; Java: 1995)

If one edge is listed (influenced), the other should be listed as well (influenced by).


 * Will you please stop adding these tenuous claims.
 * The various forms of for-each loop construct have been around in many languages, not just the ones you've heard of.
 * To show that " influenced " it would be necessary to show that took its inspiration from, not merely that both and had lifted it from the same place, usually Smalltalk or Scheme.
 * There is almost nothing original in any language you've heard of. Popular and long-lived languages are those with the wrinkles ironed out. Almost always this means that they weren't the ones that innovated a feature (in a way that's probably slightly awkward and hindsight would change), they're the ones that borrowed a feature from a language nearer the bleeding edge of language development.
 * Also, Stackoverflow is a place for first year students in Indian colleges to crib answers from their supposed experts: second year students. It's far from an accurate source, either technically or historically. Andy Dingley (talk) 10:39, 5 November 2014 (UTC)

 * I'd certainly keep an examples section, and the Hello World that's there is OK pretty much as it stands.
 * There is room for improving the Examples though. Examples should be strongly relevant and should illustrate "typical Java" - maybe a Servlet? Their point would be to illustrate some flavour of the language, and to contrast what it does differently from other languages, particularly C++.  I'm not keen on the current examples that are largely comments (that indicates they're an example that's too much about a narrow specific aspect, not about "Java" broadly at this level). Nor am I keen on the long dissection of these examples following them and being used to explain each language statement.
 * This is an encyclopedic article on Java. It's not a tutorial, it's not even the introduction to a tutorial. It should remain an overview. What is Java, what is it typically used for, which language family does it fit into, how do similar commonplace tasks (and I think a Servlet is good) look different in Java from a similar task in C++ / .NET families.
 * I don't see Wikiversity as relevant. WP articles should set out to be workable encyclopedia article in isolation. We should link to Wikiversity, not rely on it. For as far as an example is useful to the encyclopedic goal, it belongs here. For anything more, such as becoming an introduction to a detailed tutorial, that belongs entirely, and from the start, elsewhere. Andy Dingley (talk) 17:46, 24 November 2014 (UTC)

Concurrent? (Well, sort of, but...)
In "Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented...". Whilst Java is certainly a language that includes support for concurrent programming it is not one of the languages that puts it up front and centre as a main or major feature of the language. In fact, in Java 8, you need to program in a different style (using streams and lambda style) to get the most benefit out of concurrency - and this is not the prevalent style of most existing Java software, libraries, etc. Java doesn't feel very 'concurrent' compared to, say, Clojure or Erlang. Java has slowly developed and included more and more features (and libraries) for concurrent programming over time, as concurrent programming has become more important. It also retains (necessarily) a set of low-level concurrency mechanisms, which are probably the most used - even though they are the least abstracted and scalable. (For example, a preference for direct use of threads, 'synchronized' and locks, over the higher-level java.util.concurrent library. Put another way, Java seems to carry with it a good deal of concurrency baggage.)  Granted that other languages, more concurrent in nature do exist on the JVM - but the JVM is not Java. Therefore, it seems odd to list 'concurrent' first. I think it is fair to say that Java is about as concurrent as it is functional (as of Java 8), so why not list 'functional' too? (But please don't - it is no more functional than Python, Ruby or Groovy.) 185.55.60.122 (talk) 13:54, 8 April 2015 (UTC)

 * Interesting.. a) Java is at least three things, and while I'm not a lawyer, I note this "Appendix A. Limited License Grant", doesn't seem to apply to the *language* Java, at least for Java 7 (and I can't find anything similar for Java 6), having, it seems, all the same clauses stating with "1. License for Evaluation Purposes" as for Java 8; there are however differences at the top:

"Specification: JSR-000924 Java® Virtual Machine Specification ("Specification") Version: 7 Status: Final Release"


 * while for Java 8 at the top:

"Specification: JSR-337 Java® SE 8 Release Contents ("Specification") Version: 8 Status: Maintenance Release"


 * That is, at least for Java 7, this applies to the VM, I guess the bytecode, but maybe they are trying to cover more for Java 8. But probably not, as I see this not linked from "The Java Language Specification, Java SE 8 Edition", only "The Java Virtual Machine Specification, Java SE 8 Edition" (as with Java 7)


 * b) The GPL protects you and would have Google, if they had used Oracle's GPLed code (they did reimplement an incompatible replacement for the JVM, called Dalvik, that they no longer use). Google wasn't sued for violating the GPL (that is also about allowing you to use the patents; and the source and binary code).

Evaluation of Page
Check a few citations. Do the links work? Is there any close paraphrasing or plagiarism in the article?
 * I commend this article for using very good citations and upholding a neutral perspective, and when there are instances of statistics, such as in the introduction when it is stated that Java is one of the most popular programming languages in use, there are 4 used citations and a link to a page with a list of the most popular used programming languages. All 69 used sources are great choices and academically neutral. Also, this page has a reputation since it was once a featured article. The very few complaints that people have had with this article were appropriately addressed in this very talk page.

Is any information out of date? Is anything missing that could be added?
 * The information is up to date, and despite the fact that the latest version of Java was developed in 2014, this article is still being editing, with the latest edits added in 2017.

String class java.lang.String class provides numbers of methods to work on string which further helps to make different operations like trimming, concatenating, converting, comparing, replacing strings etc.

Some of the important methods associated with this class are: 1) toUpperCase: It helps to convert string into upper case letters. 2) toLowerCase: It helps to convert string into lower case letters. 3) trim: It removes white spaces before and after string. 4) startsWith and endsWith: It is used to check starting and ending characters in a string. 5) CharAt: It returns character at specified index. 6) length: It returns length of the string. 7) replace: It replaces certain characters in String with others.

JSP is not a special class.
JSP is a technology that allows implementing the business logic and the view in the JSP Model 1 architecture; or, just the view in the JSP Model 2 architecture. In either case, a JSP source document is "converted" into a servlet so that a web/servlet container can deliver it as a web page. Right now it is listed in the "special classes" section when, clearly, it is not a class. It must be placed into a sub-section of servlet at the most. — Preceding unsigned comment added by George Rodney Maruri Game (talk • contribs) 20:59, 24 November 2017 (UTC)

Clarification please
The history (second paragraph) says "Major web browsers soon incorporated the ability to run Java applets within web pages, and Java quickly became popular, while mostly outside of browsers, that wasn't the original plan. In January 2016, Oracle announced that Java runtime environments based on JDK 9 will discontinue the browser plugin."

I don't understand "while mostly outside of browsers, that wasn't the original plan". Is that saying that Java was mostly used outside browser initially? That sure is not how I remember things.

I am sure that people that already know the material being explained here know what "Java runtime environments based on JDK 9" means but for those of us that want to be educated, if that part could also be clarified then that will help. Sam Tomato (talk) 21:29, 7 April 2017 (UTC)

Making space for up-to-date info
The article has become quite out of date. In particular it included large sections with code samples for what are now semi-obsolete technologies (applets are deprecated, servlets are largely replaced by JAX-RS/JAX-WS and all the frameworks like Spring, Swing GUI went out of favour in Java for JavaFX which is now itself out of favour). So the information is low value and complicates the page, but it is also redundance, because it can be found on the main pages for those technologies.

So I have gone ahead and removed the code samples and added Main Article templates. I hope this will clear up space for better future material on modern Java, and that readers will be less mislead about what current Java involves.Rick Jelliffe (talk) 02:32, 3 May 2018 (UTC)

Influenced By
Should Simula be added to the list of languages that influenced Java? As far as I remember, Simula is the first object oriented language, including inheritance, constructors, etc. The Wikipedia page of Simula states that "The influence of Simula is often understated, and Simula-type objects are reimplemented in C++, Object Pascal, Java, C# and several other languages. "Danieldanielcolo (talk) 08:48, 25 June 2018 (UTC)
 * No, as there's no direct influence. OO was so well established 5 years before Java (and Oak), and it was well established as a bolt-on to the existing languages such as C and Pascal. I wouldn't even include Smalltalk as an OO influence (much of what influenced C++ was perhaps from Simula, but more stringly via Smalltalk). Nor Eiffel. The most important, and somewhat novel, OO aspect which Java picked up would be the handling of MI through interfaces, thus steering a midway path between Eiffel-like avoidance of it, and the mess of C++ with MI of implementation classes. If Java's OO has a "flavour", it's of being one of the first to encourage mixins as a pattern. Andy Dingley (talk) 09:34, 25 June 2018 (UTC)
 * Ok, this sounds reasonable to me; so be it.Danieldanielcolo (talk) 12:20, 26 June 2018 (UTC)

Sarcasm
This writer is really sarcastic.

This is a comment not a discussion. Bukhara (Kingdom of Bukhara) (talk) 13:15, 8 November 2018 (UTC)

Such a multi-talented guy.
As it reads, this article currently lists the creator of Java as Ryan Gosling....and I think it should be James Gosling. Right? — Preceding unsigned comment added by 72.174.3.117 (talk) 16:48, 3 February 2019 (UTC)

Nomination of Portal:Java (programming language) for deletion
A discussion is taking place as to whether Portal:Java (programming language) is suitable for inclusion in Wikipedia according to Wikipedia's policies and guidelines or whether it should be deleted.

The page will be discussed at Wikipedia:Miscellany for deletion/Portal:Haskell (programming language) (it's part of a bundled nomination) until a consensus is reached, and anyone is welcome to contribute to the discussion. The nomination will explain the policies and guidelines which are of concern. The discussion focuses on high-quality evidence and our policies and guidelines.

Users may edit the page during the discussion, including to improve the page to address concerns raised in the discussion. However, do not remove the deletion notice from the top of the page. North America1000 00:42, 26 March 2019 (UTC)

Hello Guys,

There´s an error in the article, first pharagraph has an edition problem. (see the help page).

It seems like the ref tag was not properly closed.

Deletion of version history
There was a discussion for the deletion of the Java version history article (linked in this article) here: Articles for deletion/Java version history. I still don't see why the article was deleted as it was not a speedy deletion process and the result of the discussion was not delete (to be fair, there was only one Delete by the one who asked for deletion, and two Keep). Furthermore, now: I ask here because it is not possible to ask why it was deleted on the talk page of the admin who deleted the page, nor the talk page of the deleted page (the latter is what is proposed on the deletion review, but the talk page do not exist anymore, of course). The result is that now the only history for this language is here: Java_(programming_language), which is bordering ridiculous. This process suck. Hervegirod (talk) 07:18, 18 June 2020 (UTC)
 * there is hardly any history at all (for a major programming language)
 * there is still absolutely no explanation as what must be put in this kind of version history languages
 * 'all other major languages have the same articles with the same version history articles (and with the same content, which should be tagged for deletion also if this one was deleted). For example: .NET Framework version history, Qt version history, the Ruby history, the version table for Python, the Google Chrome version history, the Firefox version history, etc... If we delete this article, we should delete all of them them too (they have exactly the same "problems")


 * It still exists on archive.org. I don't remember any delete request warning being posted.  Someone should investigate this mess.  •  Sbmeirow  •  Talk  • 07:39, 18 June 2020 (UTC)
 * https://web.archive.org/web/20200614061925/https://en.wikipedia.org/wiki/Java_version_history
 * https://en.wikipedia.org/wiki/Wikipedia:Articles_for_deletion/Java_version_history
 * I added an OR tag to this article Versions section. At least maybe people will try to help. The discussion on the Java version history article deletion here seems to go nowhere. Hervegirod (talk) 10:57, 20 June 2020 (UTC)

Merger proposal (2020)
I propose to merge Java version history into Java (programming language). I see this as the natural follow up to Articles for deletion/Java version history which was recently closed as keep. There is important information on Java version history, but the state of reliable sources about the subject remains unclear. helpfully linked to some sources at the deletion discussion, and I believe those sources are an excellent reason to include this information here, but I still don't see the logic in maintaining version history as a separate article. None of the sources provided are about Java version history, they're about modifications to the Java programming language that were made with each new version; precisely the type of information that belongs in the the history section of this article. That's an important distinction that wasn't stressed enough in the deletion discussion. Java version history as it exists now is just too much of a violation of WP:NOTDIRECTORY, with far too little notability of the subject itself, to qualify for an individual article, and the series of keep per x votes with little or no explanation following the relisting, don't change that. --<u style="color:#0000ff"> Puzzledvegetable <sup style="font-family:Century Gothic">Is it teatime already?  16:50, 3 July 2020 (UTC)

Discussion
Vote NO MERGE - only because this is being used as an alternate way to delete the "Java version history" article right after it was voted down. • Sbmeirow  •  Talk  • 17:33, 3 July 2020 (UTC)
 * "[V]oted down" is too strong. Deletion discussions are supposed to seek WP:CONSENSUS, rather than count votes. The discussion was relisted due to lack of consensus, and nothing changed. Nearly every subsequent edit fell under the category of WP:NOTARG. The discussion, which was closed by a non-sysop, should have been closed as no consensus or else left for a more experienced sysop to close. Ordinarily, this would warrant renomination, but seeing as I don't actually agree with the nom that it warrants deletion, I am seeking consensus about a merger instead. --<u style="color:#0000ff"> Puzzledvegetable <sup style="font-family:Century Gothic">Is it teatime already?  18:44, 3 July 2020 (UTC)
 * no merge This article is already long enough. --Salix alba (talk): 21:49, 3 July 2020 (UTC)
 * no merge Agree, this article is already long enough. peterl (talk) 06:22, 4 July 2020 (UTC)
 * Speedy close as the proposal would be in gross violation of WP:SIZERULE – unless of course this would actually be an end run around the recent deletion discussion as has already been suspected here, with the vast majority of the article in question's content being removed. Modernponderer (talk) 01:43, 8 July 2020 (UTC)
 * no merge I agree this seems like someone trying to weasel around the earlier deletion being shotdown. *IF* I were to even entertain this idea (and it totally violates several things including WP:SIZERULE), I would rather see it merged in the other direction where the Java language history is merged into the larger Java platform history. Merging the platform history into the language history seems like a good way to subsequently remove the platform history as it would no longer be on topic after the merge and could be removed over time. —Uzume (talk) 14:26, 10 July 2020 (UTC)
 * No merge this is pretty obviously too long to belong on the main page unless the information is shortened greatly, which I think would be a mistake. 172.73.179.154 (talk) 15:59, 10 July 2020 (UTC)
 * If you people are going to merge, kindly merge all contents. As belong to java world, this page is really helpful for us. — Preceding unsigned comment added by 122.173.61.65 (talk) 10:39, 11 July 2020 (UTC)

implementation dependencies
The lead section says "designed to have as few implementation dependencies as possible". Can we add some clarification as to what this means? Are these implementation dependencies referring to implementation of the language itself (JVM) or programs written in Java? 2600:1702:2BE0:CB80:95B0:AB36:5DEF:1924 (talk) 04:34, 30 April 2022 (UTC)
