External links modified

Hello fellow Wikipedians,

I have just modified one external link on Java collections framework. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

Added archive https://web.archive.org/web/20110807042032/http://www.digilife.be/quickreferences/PT/Java%20Collections%20Framework.pdf to http://www.digilife.be/quickreferences/PT/Java%20Collections%20Framework.pdf

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

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)[reply]

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.
