Bitwise Right Shift Operators in Java Last Updated : 08 Mar, 2023 Summarize Comments Improve Suggest changes Share Like Article Like Report Try it on GfG Practice In C/C++ there is only one right shift operator '>>' which should be used only for positive integers or unsigned integers. Use of the right shift operator for negative numbers is not recommended in C/C++, and when used for negative numbers, the output is compiler dependent. Unlike C++, Java supports following two right shift operators. Here we will be discussing both of right shift operators as listed: Signed right shift ">>"Unsigned right shift ">>>"Type 1: Signed Right Shift In Java, the operator '>>' is signed right shift operator. All integers are signed in Java, and it is fine to use >> for negative numbers. The operator '>>' uses the sign bit (leftmost bit) to fill the trailing positions after the shift. 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, if the binary representation of a number is 10....100, then right shifting it by 2 using >> will make it 11.......1. Example: Java // Java Program to Illustrate Signed Right Shift Operator // Main class class GFG { // Main driver method public static void main(String args[]) { int x = -4; System.out.println(x >> 1); int y = 4; System.out.println(y >> 1); } } Output-2 2Type 2: Unsigned Right Shift Operator In Java, the operator '>>>' denotes unsigned right shift operator and always fill 0 irrespective of the sign of the number. Example: Java // Java Program to Illustrate Unsigned Right Shift Operator // Main class class GFG { // main driver method public static void main(String args[]) { // x is stored using 32 bit 2's complement form. // Binary representation of -1 is all 1s (111..1) int x = -1; // The value of 'x>>>29' is 00...0111 System.out.println(x >>> 29); // The value of 'x>>>30' is 00...0011 System.out.println(x >>> 30); // The value of 'x>>>31' is 00...0001 System.out.println(x >>> 31); } } Output7 3 1 Time Complexity: O(1). Space Complexity: O(1) as no extra space has been used.
