What is Java Collection Framework?

[Truster]

Hello Guys,

I am studying Object oriented programming. In which the portion of C++ programming is completed and just started Java language. I know about the frame concept of java, but the 'Java Collection Framework' is entirely new concept for me. I am totally confused while understanding this concept. Does anybody know anything about the ' Java Collection Framework'? If yes then please let me know that. Your hello would be appreciable.

In the 'Java Collections Framework', the interfaces Collection & map are distinct in the hierarchy. The typical application of map is for to allow access to values stored by keys. The Java collections framework is nothing but the set of interfaces and classes that offers an easy method to store collections of objects. The Java Collection Framework is made up of a set of interfaces for working with the groups of objects. The different interfaces describe the different types of groups.

Hi friend,

The main purpose of Java collection framework is to store and retrieve objects and iterate.The Collection Framework provides a standard programming interface to many of the most common abstractions. Hence we have collections lists and maps to facilitate different forms for storage and retrieval process. Collections are for storing a sequence of object references, whereas Maps provide a key-value pair mapping to objects.

"Java Collection Framework" is nothing but a standard framework for developing new data structures that are interoperable. This new framework adds a new degree of maturity to the Java programming language, by providing a more-useful data structure API consistent. It allows for interoperability among unrelated APIs, reduces effort in designing and learning new APIs. It is very easy interfaces along with implementations that can be transparently substituted to improve application performance.

A Java Collection Framework comprises various interfaces and classes. In which allows duplicates and introduces positional indexing. The Collection Framework is made up of a set of interfaces for working with the groups of objects. It also provides a wide variety of data structures, for those who don't want to write their own. The Collection Framework provides a well-designed set of interface and classes for sorting and manipulating groups of data as a single unit a collection.
