What are the main shift operators provided by Java? Explain with an example?

Java provides three shift operators namely −

• Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by the right operand.

• Binary Right Shift Operator. The left operands value is moved right by the number of bits specified by the right operand.

• Shift right zero fill operator. The left operands value is moved right by the number of bits specified by the right operand and shifted values are filled up with zeros.

Example

 Live Demo

public class Test {
   public static void main(String args[]) {
      int a = 60;/* 60 = 0011 1100 */
      int b = 13;/* 13 = 0000 1101 */
      int c = 0;
      c = a << 2; /* 240 = 1111 0000 */
      System.out.println("a << 2 = " + c );
      c = a >> 2; /* 15 = 1111 */
      System.out.println("a >> 2 = " + c );
      c = a >>> 2; /* 15 = 0000 1111 */
      System.out.println("a >>> 2 = " + c );
   }
}

Output

a << 2 = 240
a >> 2 = 15
a >>> 2 = 15
