The collections framework is a unified architecture for representing and manipulating collections, allowing them to be manipulated independently of the details of their representation. It reduces programming effort while increasing performance. It allows for interoperability among unrelated APIs, reduces effort in designing and learning new APIs, and fosters software reuse. The framework is based on fourteen collection interfaces. It includes implementations of these interfaces, and algorithms to manipulate them.Overview
- Overview - An overview of the Collections framework.
- API Reference - An annotated outline of the classes and interfaces comprising the collections framework, with links into the JavaDoc.
- Tutorial - A tutorial introduction to the collections framework with plenty of programming examples.
- API Enhancements in Java SE 6 - An annotated list of API changes between the 5.0 and 6 releases.
- API Enhancements in J2SE 5.0 - An annotated list of API changes between the 1.4 and 5.0 releases.
- API Enhancements in J2SDK 1.4 - An annotated list of API changes between the 1.3 and 1.4 releases.
- Design FAQ- Answers to frequently asked questions concerning the design of the collections framework.

More formally, adds the specified element e to this set if the set contains no element e2 such that (e==null ? e2==null : e.equals(e2)). If this set already contains the element, the call leaves the set unchanged and returns false. In combination with the restriction on constructors, this ensures that sets never contain duplicate elements.
