What is the difference between ‘>>’ and ‘>>>’ operators in java?

Answer»

These 2 are the BITWISE right shift OPERATORS. Although both operators LOOK similar. But there is a minimal difference between these two right shift operators.

  • ‘>>’ Bitwise Right Shift Operator- This operator shifts each bit to its right position. And this maintains the signed bit.
  • ‘>>>’ Bitwise Right Shift Operator with trailing ZERO- This operator also shifts each bit to its right. But this doesn’t maintain the signed bit. This operator makes the Most significant bit to 0.

Example- Num1 = 8, Num2 = -8.

So the binary form of these numbers are - 

Num1 = 00000000 00000000 00000000 00001000 
Num2 = 11111111 11111111 11111111  11111000

‘>>’ Operator : 8 >> 1 (Shift by one bit) : 

Num1 = 00000000 00000000 00000000 00000100
Num2 = 11111111 11111111 11111111  11111100

‘>>>’ Operator : 8 >>> 1 (Shift by one bit) = 

Num1 = 00000000 00000000 00000000 00000100
Num2 = 01111111 11111111 11111111 11111100
