The Java Collection Framework (JCF) gives you ready-made data structures. It stores and manages groups of objects.

You do not write data code from scratch. This makes your work faster.

Core components:

  • Interfaces: These define standard behaviors.
  • Classes: These are the tools you use.
  • Algorithms: These handle sorting and searching.

Common tools:

  • Interfaces: List, Set, Map, and Queue.
  • Classes: ArrayList, HashSet, HashMap, and PriorityQueue.

Why this helps you:

  • It resizes automatically.
  • It cuts repetitive code.
  • It makes your code easy to maintain.
