Java - Long rotateRight() method

Description

The Java Long rotateRight() method returns the value obtained by rotating the two's complement binary representation of the specified long 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.Long.rotateRight() method

public static long rotateRight(long i, long distance)

Parameters

  • i − This is the long 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 long value right by the specified number of bits.

Exception

NA

Example 1

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

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

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

Output

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

2305843009213693952
144115188075855872
9007199254740992

Example 2

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

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

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

Output

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

-1152921504606846977
-72057594037927937
-4503599627370497
-281474976710657

Example 3

The following example shows the usage of Long rotateRight() method to get an long by rotating the two's complement binary representation of the specified long value i right by the specified number of bits. We've created a long 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 LongDemo {
   public static void main(String[] args) {
      long n = 0L;

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

Output

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