Answer Posted / dipal mehta

The above one is a right answer but the reader who reads it
for referance plz Note line :

I1 i1=new sample();
i1.add();

This might confusing but It means that We have created
object of I1 interface class but with sample as a assigned
object which is valic in this case.
Now call of i1.add() will call the method of interface I1
which points to or defined in Sample class
This will more clearer if you will append two or three more
simple methods like subtract() and try to call it as above
one which actually a part of Mostly used Multiple
Inheritance funda.
personally speaking it will benefitial to you if try
yourself
Hope readers like tips
