![]() So why do you think we need Java collections? The Java collection framework provides the developers to access prepackaged data structures as well as algorithms to manipulate data. Algorithms are polymorphic in nature as the same method can be used to take many forms or you can say perform different implementations of the Java collection interface. Also, they form a hierarchy in object-oriented programming languages.Ĭlasses: Classes in Java are the implementation of the collection interface. It basically refers to the data structures that are used again and again.Īlgorithm: Algorithm refers to the methods which are used to perform operations such as searching and sorting, on objects that implement collection interfaces. They allow Java collections to be manipulated independently from the details of their representation. Interfaces: Interface in Java refers to the abstract data types. A Java collection framework includes the following: Let’s get started with the first topic in the Java collections blog.Ī Java collection framework provides an architecture to store and manipulate a group of objects. Now, let us move ahead in this Java collections blog, where we will understand each aspect of it in the following sequence: You can perform all operations such as searching, sorting, insertion, manipulation, deletion, etc., on Java collections just like you do it on data. ![]() What are Java collections? Java collections refer to a collection of individual objects that are represented as a single unit.
