Inter Face

In Java, an interface serves as a blueprint for classes, containing static constants and abstract methods. It facilitates abstraction, multiple inheritance, and loose coupling by allowing classes to depend on behavior rather than implementation. Interfaces define a set of behaviors that implementing classes must adhere to, often representing an IS-A relationship.

In Java, an interface is a blueprint of a class ..

A Java interface contains static constants and


abstract methods.

The need for interfaces in Java arises from several key aspects of object-oriented programming:

 The interface in Java is a mechanism to achieve abstraction.

 By default, variables in an interface are public, static, and final.

 It is used to achieve abstraction and multiple inheritance in Java.

 It supports loose coupling (classes depend on behavior, not implementation).

 In other words, interfaces primarily define methods that other classes must implement.

 An interface in Java defines a set of behaviours that a class can implement, usually
representing an IS-A relationship, but not always in every scenario.
