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).
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.
