Java application programming interface (API) is a list of all classes that are part of the Java development kit (JDK). It includes all Java packages, classes, and interfaces, along with their methods, fields, and constructors.


Application program interface (API) is a set of routines, protocols, and tools for building software applications. An API specifies how software components should interact. Additionally, APIs are used when programming graphical user interface (GUI) components. A good API makes it easier to develop a program by providing all the building blocks. A programmer then puts the blocks together,and build his own application. An example, You are buying an item in online through your credit card. You will provide credit card details and press continue button. It will tell you whether your information is correct or not. To provide these results, there are lot of things in the background.The application will send your credit card details to a remote application which will validate your information and send the result back your application. API is used in this scenario. Java application programming interface (API) is a list of all classes that are part of the Java development kit (JDK). It includes all Java packages, classes, and interfaces, along with their methods, fields, and constructors. These pre-written classes provide a tremendous amount of functionality to a programmer.

API stands for Application Programming Interface. So it is an interface through which your application talks to it. A Java API would mean that your application talks to Java using that interface. A .NET API would mean using that interface you talk to .NET.

An API means Application Programming Interface. API is a collection of pre-developed Interfaces and Classes which are helped for a developer to develop java applications easily and fastly.


Dictionary definition : “a set of functions and procedures that allow the creation of applications which access the features or data of an operating system, application, or other service.”
