Question

Given:

Question Image

and the following code fragment:

S2 sobj = new S2();  
sobj.display(10, 100);

What is the result?

A Child 10 Child 100 Parent 100
B Parent 10 Child 10 Parent 1000
C Child 10 Parent 100 Parent 100
D A compile time error occurs.

Explanation

Calls made through this or without a qualifier use dynamic method dispatch, so both one-argument calls execute S2.display(int) and print Child 10 and Child 100. The super.display(y) call explicitly invokes S1.display(int), which prints Parent 100.
