WebWe can use shift operators if we divide or multiply any number by 2. The general format to shift the bit is as follows: variable << or >> number of places to shift; For example, if a=10. a>>2; //shifts two bits. a>>4; //shifts 4 bits. Java provides the following types of shift operators: Signed Right Shift Operator or Bitwise Right Shift Operator. WebRight Shift. The bitwise right shift operator ( >>) is analogous to the left one, but instead of moving bits to the left, it pushes them to the right by the specified number of places. The rightmost bits always get dropped: Every time you shift a bit to the right by one position, you halve its underlying value.
