The "Stack" section is misleading
The Stack and Vector classes are not part of the Collections framework. They are legacy, from Java 1.0, and should not be used in new code. Suggest removing this section, or clarifying that these classes are _not_ to be used. 128.237.187.136 (talk) 16:09, 24 November 2017 (UTC)

Towards the end of this section, it states

"The usual push and pop operations are provided, as well as a method to peek at the top item on the stack, a method to test for whether the stack is empty, and a method to search the stack for an item and discover how far it is from the top."

It would be helpful to specify what these methods are.

Queue Interfaces
The sections states: "But it also has the Queue methods". Again, I think it would be helpful to specify what these methods are.

Also: The description of blocking queue is unclear. It states, very unhelpfully that additions and removals are "blocking"(???). This is not an explanation at all.

Figure of the Map class and interface hierarchy is incorrect
There is an issue in the figure of the java.util.Map class and interface hierarchy. NavigableMap and SortedMap are interfaces and should be marked with yellow circle rather than blue rectangle. This is misleading because it make you think that TreeMap may inherit from two classes, which is impossible in Java. — Preceding unsigned comment added by 132.64.34.178 (talk) 12:53, 27 June 2018 (UTC)
