// multiple inheritance using interface
// because interface contains only abstract methord , which impliments is provided by the sub classes.
// we can not use this class c extends a,b . we can use class c implements a,b.

//class A{
//    void show(){
//        System.out.println("This is class A");
//    }
//}
//class B{
//    void show(){
//        System.out.println("This is class B");
//    }
//}
//class Multiple extends A,B // error
//{
//    public static void main(String[] args) {
//        Multiple m = new Multiple();
//        m.show();
//    }
