In Java, Collection is a framework that provides an architecture to store and manipulate groups of objects. The “Collection Framework” has been defined in JDK 1.2 and it holds all the collection classes and interfaces in it. The two main interfaces of the Java Collection classes are the Collection interface (java.util.Collection) and the Map interface (java.util.Map). Java Collections can perform all operations on data such as searching, sorting, insertion, manipulation, and so on.
