While dealing with (+)ve numbers there is no difference between >>> and >> operators.Both operators shift zeros into the upper bits of a number.

The difference arises when dealing with (-)ve numbers.Since (-)ve numbers,(-)ve numbers have their high order bit set to 1.The >>> (Zero Fill Shift Operator) shifts zeros into all the upper bits,INCLUDING THE HIGH ORDER BIT,Thus making the (-)ve number into a (+)ve number.
