Java Collections API

Did you know that Java 5 and 6 added 8 new interfaces and 16 new collection implementations to the JDK, more than doubling the size of the collection API? Collections 201 gives you an update on all of the interfaces, implementations, and utilities and gives you guidance on picking the perfect collection. In particular, Java 5 introduced a new major collection type Queue and a whole new java.util.concurrent package with data structures optimized for concurrent use.

This presentation will give an overview of the major collection types, with a particular focus on additions in Java 5 and 6 with interfaces like Queue, Deque, NavigableSet as well as new implementations like ConcurrentHashMap, ConcurrentSkipListSet/Map, and the family of Queue implementations like LinkedBlockingQueue.

In addition to covering the interfaces and implementations, we will also look at the backing data structures, iterator types, concurrency and performance concerns, and more.
