public static void main(String args[])

{

int x = -1;

int y1 = x >>> 16;

int y2 = x >> 16;

System.out.print(“\n\nApplying >> on -1,16 times”);

System.out.println(“ give “ + y2);

System.out.print(“\nApplying >>> on -1,16 times”);

System.out.println(“ give “ + y1);

}

}

OUTPUT:

Applying >> on -1, 16 times give -1

Applying >>> on -1, 16 times give 65535
