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

The Java Iterator is an all-purpose interface that simplifies looping through a collection of objects. Java's ListIterator provides all the functionality of the Iterator interface, with four ...

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).

In this Java 101 tutorial, I’ve explained how interfaces differ from classes, and showed you how to declare, implement, and extend interfaces in your Java programs.

At the base of the Framework are the interfaces java.util.Collection and java.util.Map. The Collection interface represents just a group of objects, with no particular order or restriction.

The Java Collections Framework (JCF), introduced in 1998 in JDK 1.2, is quickly becoming the standard for storing dynamic data in Java systems. Many new APIs use JCF’s container interfaces to ...
