What is collection framework in java?

The collection framework in Java is used to store data and process it efficiently. It is nothing but a collection of interfaces and classes.

The collection interface is subdivided into the list, set, map, sorted map, sorted set, and enumeration. These interfaces present a unified architecture for representing and manipulating a collection of data. This framework has high-performance in implementing fundamental collections such as dynamic arrays, linked lists, trees, and hashtables efficiently.
