   int x = 10; 
   static int y = 20; 
}

   static int y = 40; 
} 

public class Main  { 
   public static void main (String [] args)  { 
     System.out.println(new MySubClass().x+
                       ", "+
                       new MySubClass().y); 
   } 
}

Select 1 option

  • A. 10, 40
  • B. 30, 20
  • C. 10, 20
  • D. 30, 40
  • E. 20, 30
  • F. Compilation error. 


Correct Option is  : D

Note

System.out.println (new MySubClass ().x);

The reference is of type MySubClass and so MySubClass's x will be accessed.
