Advertisements


Description

The java.lang.Long.reverseBytes() method returns the value obtained by reversing the order of the bytes in the two's complement representation of the specified long value.

Declaration

Following is the declaration for java.lang.Long.reverseBytes() method

public static long reverseBytes(long i)

Parameters

  • i -- This is the long value.

Return Value

This method returns the value obtained by reversing the bytes in the specified long value.

Exception

  • NA

Example

The following example shows the usage of java.lang.Long.reverseBytes() method.

package com.tutorialspoint;

import java.lang.*;

public class LongDemo {

   public static void main(String[] args) {

     long l = 210;
     System.out.println("Number = " + l);
    
     /* returns the string representation of the unsigned long value 
     represented by the argument in binary (base 2) */
     System.out.println("Binary = " + Long.toBinaryString(l));

     /* returns the value obtained by reversing the bytes in the specified
     long value */ 
     System.out.println("After reversing = " + Long.reverseBytes(l));
   }
}

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

Number = 210
Binary = 11010010
After reversing = -3314649325744685056
