Java collection framework provides you with the complete architecture of objects. Java frameworks group of objects includes – classes, interfaces, and algorithm.

The Set interface inherits its methods from Collection (java.util.Collection) and contains only those methods. In addition to sets, there are queues (java.util.Queue) and maps (java.util.Map).

Proposal for enhancing the Java programming language would define interfaces for sequenced collections, sequenced sets, and sequenced maps.

The Java 2 SDK organizes its vast collection of classes and interfaces into a tree-like hierarchy of packages within packages, which is equivalent to directories within directories.
