Java unsigned shift (>>>) and signed Shift (>>)

>> (<<) in Java represents a signed shift. <<< (>>>) denotes unsigned shift

Such as:

int num = 22;

Binary is 0001 0110, num>>>1, right shift one becomes 0000 1011 (11)

int num =-22

Binary with complement: 1110 1001, num >>>1 unsigned Right shift one: 0111 0100

>> After moving right, the leftmost symbol is used as a substitute. >>> move right to the left with 0 alternates

Output

temp = 2147483637
temp =-11
