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).

The interfaces java.util.List and java.util.Set extend Collection, representing more specialized data structures and adding more operations and/or constraints. List represents a sequence of ...

The Java Collections Framework provides insight into the usefulness of nesting one interface in another. Consider the java.util.Map interface, which describes a map (a collection of key-value pairs).

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.

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 ...
