A Collection in simple terms means when a group of similar things, often a group created by someone is known as a collection. A collection when collected works like a container – it groups multiple similar elements into a single unit. Forming a natural group they can be stored, modify, redeem, recover and communicate aggregate data.

Java provides a collection framework defining several groups and interfaces to represent groups of objects as a single unit. Collection framework is one of the central and fundamental parts of Java programming language.
