Jun 26, 2024 · In Java, a separate framework named the “Collection Framework” has been defined in JDK 1.2 which holds all the Java Collection Classes and Interface in it. In Java, the Collection interface (java.util.Collection) and Map interface (java.util.Map) are the two main “root” interfaces of Java collection classes.
The Java collections framework provides a set of interfaces and classes to implement various data structures and algorithms. For example, the LinkedList class of the collections framework provides the implementation of the doubly-linked list data structure.
A collections framework is a unified architecture for representing and manipulating collections, enabling collections to be manipulated independently of implementation details. The primary advantages of a collections framework are that it:
A collection is an object that represents a group of objects (such as the classic ArrayList class). The Java Collections Framework enables interoperability among unrelated APIs, reduces effort in designing and learning new APIs, and fosters software reuse.
The Collections Framework is an implementation of the concepts on how to store, organize, and access data in memory that were developed long before the invention of Java. The Collections Framework does this in a very efficient way, as you are going to see.
A collections framework is a unified architecture for representing and manipulating collections. All collections frameworks contain the following − Interfaces − These are abstract data types that represent collections.
