Java - Design Pattern - Multiple Inheritance

<source lang="Java"> // A simple Java program to demonstrate multiple // inheritance through default methods. interface PI1 {

   // default method 
   default void show() 
   { 
       System.out.println("Default PI1");

   default void show()

// Implementation class code class TestClass implements PI1, PI2 {

   // Overriding default show method 
   public void show()

       // use super keyword to call the show 
       // method of PI1 interface 
       PI1.super.show();
