Question

Greetings,

I’ve been working out of an embedded version of Java where the height of complex structures included in the API was a vector or queue. This usually meant writing structures from scratch when needed.

I am now coming back to the land of the living, I will have full access to a real version of java with all the bells and whistles. This however presents a new problem, the API is quite large.

I was wondering if anyone could tel me about essential data structures which have come to existence in the last 2 years. I’m talking about lists, maps, tree’s etc. structures that can handle concurrency and structures.

From what I remember there was a concurrency library however some standard collection structures also had concurrency aspects put in place.

Answer 1

Start with the Java Collections Trail

http://java.sun.com/docs/books/tutorial/collections/index.html

This will go over all of the basics.

Then once you’re happy take a look at the Concurrent Collections Trail

http://java.sun.com/docs/books/tutorial/essential/concurrency/collections.html

However it would also be a good idea to look at the Concurrency package as well.
