Java Collection Framework
The Java Collections Framework is a library of classes and interfaces for working with collections of objects A collection is an object which can store other objects called elements Collections provide methods for adding and removing elements and for searching for a particular element within the collection |
How to decide which collection to use in Java?
Choose the Right Collection Interface
Sets are used when elements are treated as a set of objects, there are no duplicates, and the insertion order doesn't matter.
Queues are used when LIFO, FIFO, or removal by priority semantics is required, and finally, maps are used when the association of keys and values is needed.Who is the founder of DurgaSoft?

Hierarchy of Collection Framework
Collection, Set, Queue, and List all are interfaces.
Set, Queue and List are extended by the Collection interface.
PriorityQueue, HashSet, LinkedList, and Stack all are classes or the implementation of these interfaces.
It is not mandatory that a class implements just one interface.
What is a collection in Java?
The Java platform includes a collections framework.
A collection is an object that represents a group of objects (such as the classic Vector class).
