Unsigned right shift operator. Java three greater than signs (>>& gt) is an unsigned right shift operator, which is used to shift the bits of a number to the right by a given number of digits. In the process of moving, the bits discarded on the left are filled with 0. It is usually used to make replacement easier when dealing with plastic data. In addition to the unsigned right shift operator, java also provides several other bit operators, such as (signed right shift operator),&; (Bitwise AND operator), | (Bitwise or operator), (Bitwise XOR operator), ~ (Bitwise negation operator) and so on.
