     Short ShortObj3 = new Short(shortNum3);
    
     // returs false as both object contains different short value
     boolean val = ShortObj1.equals(ShortObj3); 
     System.out.println("shortObj1 and shortObj3 have same value : " + val);

     // returns true as both object contains same short value
     val = ShortObj1.equals(ShortObj2); 
     System.out.println("shortObj1 and shortObj2 have same value : " + val);
