Difference between >> and >>> operator. Both >> and >>> are used to shift the bits towards the right. The difference is that the >> preserve the sign bit while the operator >>> does not preserve the sign bit. To preserve the sign bit, you need to add 0 in the MSB.
The >>> operator is the unsigned right bit-shift operator in Java. It effectively divides the operand by 2 to the power of the right operand, or just 2 here.
The unsigned right shift operator ( >>> ) (zero-fill right shift) evaluates the left-hand operand as an unsigned number, and shifts the binary representation of that number by the number of bits, modulo 32, specified by the right-hand operand.
It is a binary operator denoted by the symbol ^ (pronounced as caret). It returns 0 if both bits are the same, else returns 1. Let's use the bitwise exclusive OR operator in a Java program.
>> is a signed right shift operator which shifts a bit pattern to the right.
>>> is an unsigned right shift operator which shifts a zero into the leftmost position. Please refer to the Oracle Docs.
