Extending Java Interfaces

Extending Interfaces:

An interface can extend another interface to inherit its property, in this case we have to use “extends” keyword:

interface My {

      void show();

}

interface My1 extends My

{

      void display();

}

public class MyImpl implements My1

{

      public void show() {

            System.out.println("Show method called.");

      }

     

      public void display()

      {

            System.out.println("Display method called.");

      }

      public static void main(String args[])

      {

            My1 m1 = new MyImpl();

            m1.show();

            m1.display();

      }

}

Output:

Show method called.

Display method called.
