Java set is a collection construct that, by definition, contains unique elements — that is, no duplicates. the java set collection can only contain objects, and it is not an ordered list, that means it does not care about the order of the elements. The java collections framework gives the programmer access to prepackaged data structures as well as to algorithms for manipulating them. a collection is an object that can hold references to other objects. the collection interfaces declare the operations that can be performed on each type of collection. Java collections framework is consist of the interfaces and classes which helps in working with different types of collections such as lists, sets, maps, stacks and queues etc. these ready to use collection classes solve lots of very common problems where we need to deal with group of homogeneous as well as heterogeneous objects.
This tutorial explains the usage of the java collections, e.g. lists, arraylists and maps with java. 1. java collections. the java language supports arrays to store several objects. an array is initialized with an predefined size during instantiation. to support more flexible data structures the core java library provides the collection framework.
