An Object that implements an Interface can be cast to the same

Interface. Since An Object implementing an Interface already

provides implementation for the methods of that Interface, it is

allowed to do so as per the rules of Inheritance

interface MyInterface{
   public static int num = 100;
   public void display();
}
public class InterfaceExample implements MyInterface{
   public void display() {
      System.out.println("This is the implementation of the display method");
   }
   public void show() {
      System.out.println("This is the implementation of the show method");
   }
   public static void main(String args[]) {
      MyInterface obj = new InterfaceExample();
      obj.display();
      //obj.show();
   }
}
