What is Java Collections?

Java Collections is a framework in Java that provides a unified architecture for representing and manipulating groups of objects. It includes interfaces (like List, Set, Map), classes (like ArrayList, HashSet, HashMap), and algorithms for common operations like searching, sorting, insertion, and deletion. Java Collections are commonly used to store, retrieve, and manage data efficiently in Java applications, offering alternatives to primitive arrays and providing higher-level data structures with built-in functionalities.
