        System.out.println("in Level 2");
  // result=100/0;  //Level 2

        try 
        {

        {

          System.out.println("In Level 3 finally");

        }


        // result=100/0;  //Level 2            
        }

      catch (Exception e) 
      {

        System.out.println("Level 2:" + e.getClass().toString());
