Bitwise Right Shift Operators in Java - GeeksforGeeks

WebShifting all of a number's bits to the left by 1 bit is equivalent to multiplying the number by 2. Thus, all of a number's bits to the left by n bits is equivalent to multiplying that number by 2 n. Notice that we fill in the spots that open up with 0s. If a bit goes further left than the place of the most-significant digit, the bit is lost. WebThe left shift operator, <<, shifts all of the bits in a value to the left a specified number of times.It has this general form: value << num. Here, num specifies the number of positions to left-shift the value in value.That is, the << moves all of the bits in the specified value to the left by the number of bit positions specified by num.For each shift left, the high-order bit … get on the groove
