• interface is a fully unimplimented class it means it does'nt have any implimentations of an object instead of it have only declarations of an object it means by using interface we are gathering a real world object requirements and further those are implimented by sub classes.
  By using interfaces we can achieve multiple inheritance.
  And we can provide a bridge between user class and sub classes.
