Interface Extending Another Interface

This program demonstrates interface inheritance.

Problem Statement

Write a Java program where AdvancedPlayable extends Playable interface.

Source Code

1	interface Playable {
2	void play();
3	}
4	interface AdvancedPlayable extends Playable {
5	void pause();
6	}
7	class MusicPlayer implements AdvancedPlayable {
8	public void play(){ System.out.println("Music playing"); }
9	public void pause(){ System.out.println("Music paused"); }
10	}
11	public class InterfaceInheritance {
12	public static void main(String[] args) {
13	System.out.println("Eduinq Interface Inheritance");
14	AdvancedPlayable mp=new MusicPlayer();
15	mp.play(); mp.pause();
16	}
17	}

Program Output

Eduinq Interface Inheritance
Music playing
Music paused

Explanation

Interfaces can extend other interfaces. - AdvancedPlayable inherits play() from Playable and adds pause(). - MusicPlayer implements both methods, showing interface inheritance. Conclusion: Shows how interfaces can extend other interfaces.
