Interface implementation l Android Development Course For Beginners l Class-22

Hello Listeners Today in this tutorial I will discuss about Interface implementation in Java

Interface implementation

The interface in Java is a mechanism for achieving 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.

You cannot instantiate an interface.
An interface does not contain any constructors.

All of the methods in an interface are abstract.

An interface cannot contain instance fields. The only fields that can appear in an interface
must be declared both static and final.

An interface is not extended by a class; it is implemented by a class.
An interface can extend multiple interfaces.
