The Java Collections Framework

Collections in java is a framework that provides an architecture to store and manipulate the group of objects.

Any activity that we do, such as searching, storing/retrieving, manipulating, adding, deleting, etc. can all be done by Java Collections.

The Collections framework contains classes, interfaces, and algorithms used to manipulate data by implementing common data structures.

A collection itself is some kind of data structure that holds these objects so that we can have an easier way to deal with them.
