Integer class reverseBytes() method

  • reverseBytes() method is available in java.lang package.
  • reverseBytes() method is used to returns the value generated by reversing the order of bytes in binary 2's complement denotation of the given argument.
  • reverseBytes() method is a static method, it is accessible with the class name too and if we try to access the method with the class object then also we will not get an error.
  • reverseBytes() method does not throw an exception at the time of reversing the order of bytes.


    public static int reverseBytes (int value);


  • int value – represents the integer value to be parsed.

Return value:

The return type of this method is int, it returns an integer value generated by reversing the bytes order in 2's complement of the given integer value.


// Java program to demonstrate the example 
// of reverseBytes(int value) method of Integer class

public class ReverseBytesOfIntegerClass {
    public static void main(String[] args) {
        int value = 1296;

        // Display value
        System.out.println("value: " + value);

        // It returns the string representation of the given 
        // unsigned integer value denoted by the argument in 
        // binary by calling Integer.toBinaryString(value)
        System.out.println("Integer.toBinaryString(value): " + Integer.toBinaryString(value));

        // It returns the value generated by reversing the order of the bytes in the 
        //given argument value by calling Integer.reverseBytes(value)
        System.out.println("Integer.reverseBytes(value): " + Integer.reverseBytes(value));


value: 1296
Integer.toBinaryString(value): 10100010000
Integer.reverseBytes(value): 268763136
