Java - Integer Class reverseBytes() Method

Integer class reverseBytes() method: Here, we are going to learn about the reverseBytes() method of Integer class with its syntax and example. By Preeti Jain Last updated : March 18, 2024

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.

Syntax

public static int reverseBytes (int value);

Parameters

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.

Example

// 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));
    }
}

Output

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