What is Collection Of Classes In Java?

In Java, the Collection Framework is a unified architecture for representing and manipulating collections of objects. It includes interfaces like List, Set, and Map, which define various data structures. Classes such as ArrayList, HashSet, and HashMap implement these interfaces, providing specific behaviors for storing, retrieving, and manipulating data. The framework also offers utility classes like Collections and Arrays for common operations. It enables developers to handle groups of objects effectively, improving code reusability and efficiency.
