Java interface Kullanımı

An interface is a description of the actions that an object can do … for example when you flip a light switch, the light goes on, you don’t care how, just that it does. In Object Oriented Programming, an Interface is a description of all functions that an object must have in order to be an “X”.

For example, in our real life, if we consider the interface to be given as an example is the air condition, bike, ATM machine, etc . Similarly, in Java, Interface also plays the same role; it is considered as an interactive medium between the system and the end-user.

A Java interface contains static constants and abstract methods . The interface in Java is a mechanism to achieve abstraction. There can be only abstract methods in the Java interface, not the method body. It is used to achieve abstraction and multiple inheritance in Java.10 Şub 2022
