What difference between signed left and unsigned right shift operators ?
or
What is difference between the >> and >>> operators ?
Answer :
Signed left shift operator(<<) : It shifts a bit pattern to the left
Signed right shift operator (>>) : It shifts a bit pattern to the right
Unsigned right shift operator (>>>) : It shifts a zero into the leftmost position and while leftmost position after “>>” depends on sign extension
Please see example below:
package com.javahonk.shiftoperator; public class ShiftOperatorTest { public static void main(String[] args) { System.out.println("Right shift opeartor(>>)"); System.out.println(" 46 >> 3 = " + (46 >> 3)); System.out.println(" -46 >> 3 = " + (-46 >> 3)); System.out.println("Left shift opeartor (<<)"); System.out.println(" -46 >> 3 = " + (-46 << 3)); System.out.println(" 46 >> 3 = " + (46 << 3)); System.out.println("Unsigned right shift opeartor (>>>)"); System.out.println(" -46 >>> 3 = " + (-46 >>> 3)); System.out.println(" 46 >>> 3 = " + (46 >>> 3)); } }
Output:
