Question

What is the output of running class C? The three Java classes are in separate Java files in the same directory (or in the same package). class A { public AO { System.out.println("The default constructor of A"); } // end A constructor } // end class A class B extends A { public BCString s) { System.out.println(s); } // end B constructor } // end class B public class C { public static void main(String[] args) { B b = new B("B rocks!"); System.out.println("Hi from C"); } // end main } end class C

Answer 1

Output-

The Default constructor of A
B rocks!
Hi from C

Explanation - We we run C program . It will start running from top . So first B b = new B("B rocks"); will run and it will go to class B. In B class by using extends it call class A so first class A will run the class A then return to class B and run program and return back to class C and run the rest of the program.
