Java - Integer rotateRight() method

Description

The Java Integer rotateRight() method returns the value obtained by rotating the two's complement binary representation of the specified int value i right by the specified number of bits. (Bits shifted out of the right hand, or low-order, side reenter on the right, or high-order.)

Declaration

Following is the declaration for java.lang.Integer.rotateRight() method

public static int rotateRight(int i, int distance)

Parameters

  • i − This is the int value.

  • distance − This is the rotation distance.

Return Value

This method returns the value obtained by rotating the two's complement binary representation of the specified int value right by the specified number of bits.

Exception

NA

Example 1

The following example shows the usage of Integer rotateRight() method to get an int by rotating the two's complement binary representation of the specified int value i right by the specified number of bits. We've created a int variable and assigned it a positive int value. Then using rotateRight() method within a for loop, we're printing new integers generated.

package com.tutorialspoint;
public class IntegerDemo {
   public static void main(String[] args) {
      int n = 2;

      // returns the value obtained by rotating right
      for(int i = 0; i < 4; i++) {
         n = Integer.rotateRight(n, 4);
         System.out.println(n);
      }
   }
}

Output

Let us compile and run the above program, this will produce the following result −

536870912
33554432
2097152
131072

Example 2

The following example shows the usage of Integer rotateRight() method to get an int by rotating the two's complement binary representation of the specified int value i right by the specified number of bits. We've created a int variable and assigned it a negative int value. Then using rotateRight() method within a for loop, we're printing new integers generated.

package com.tutorialspoint;
public class IntegerDemo {
   public static void main(String[] args) {
      int n = -2;

      // returns the value obtained by rotating right
      for(int i = 0; i < 4; i++) {
         n = Integer.rotateRight(n, 4);
         System.out.println(n);
      }
   }
}

Output

Let us compile and run the above program, this will produce the following result −

-268435457
-16777217
-1048577
-65537

Example 3

The following example shows the usage of Integer rotateRight() method to get an int by rotating the two's complement binary representation of the specified int value i right by the specified number of bits. We've created a int variable and assigned it a zero value. Then using rotateRight() method within a for loop, we're printing new integers generated.

package com.tutorialspoint;
public class IntegerDemo {
   public static void main(String[] args) {
      int n = 0;

      // returns the value obtained by rotating right
      for(int i = 0; i < 4; i++) {
         n = Integer.rotateRight(n, 4);
         System.out.println(n);
      }
   }
}

Output

Let us compile and run the above program, this will produce the following result −
