The Java Collections Framework

JDK 1.2 Contents

The Java Collections API is a unified framework for representing and manipulating collections, allowing them to be manipulated independently of the details of their representation. It allows for interoperability among unrelated APIs, reduces the effort in designing and learning new APIs that would otherwise have their own collection interfaces, and fosters software reuse. The API includes interfaces, concrete implementations, abstract implementations, and a few polymorphic algorithms.
