Differences

1.Difference between >> and >>>:

The >> is signed right shift operator. The right shift operator >> shifts all of the bits in a

value to the right a specified number of times. Rightmost bit is lost when this shift occur.

leftmost position after ">>" depends on sign extension. If the number is negative, then 1 is used

as a filler and if the number is positive, then 0 is used as a filler.

For example:

int a = 35;

a = a >> 2; // a now contains 8

00000000 00000000 00000000 00100011 35 >> 2

00000000 00000000 00000000 00001000 8

int a = -8;

a = a >> 1; // a now contains -4

11111111 11111111 11111111 11111000 –8 >>1

11111111 11111111 11111111 11111100 –4

 The >>> is right shift unsigned operator. It shifts bits towards right. Zeros are fill in the left

bits regardless of sign.

For example:

int a = -1;

a = a >>> 24;

11111111 11111111 11111111 11111111 –1 in binary as an int

>>>24

00000000 00000000 00000000 11111111 255 in binary as an int
