Apache Commons Collections - Extended Collections API for Java

The Java Collections Framework was a major addition in JDK 1.2. It added many powerful data structures that accelerate development of most significant Java applications. Since that time it has become the recognized standard for collection handling in Java.

Commons Collections seek to build upon the JDK classes by providing new interfaces, implementations and utilities. There are many features, including:

 * Bag interface for collections that have a number of copies of each object
 * BidiMap interface for maps that can be looked up from value to key as well
   and key to value
 * MapIterator interface to provide simple and quick iteration over maps
 * Transforming decorators that alter each object as it is added to the
   collection
 * Composite collections that make multiple collections look like one
 * Ordered maps and sets that retain the order elements are added in,
   including an LRU based map
 * Reference map that allows keys and/or values to be garbage collected under
   close control
 * Many comparator implementations
 * Many iterator implementations
 * Adapter classes from array and enumerations to collections
 * Utilities to test or create typical set-theory properties of collections
   such as union, intersection, and closure
