Character.reverseBytes() in Java with examples

java.lang.Character.reverseBytes() is a built-in method in java which returns the value obtained by reversing the order of the bytes in the specified char value.

Syntax:

public static char reverseBytes(char ch)

Parameter: The function accepts one mandatory parameter ch which signifies the character whose order of bytes is to be reversed.

Returns: This method returns the value obtained by reversing (or, equivalently, swapping) the bytes in the specified char value.

Below programs illustrate the java.lang.Character.reverseBytes() function:
Program 1:

// Java program to demonstrate the
// Character.reverseBytes() when a

import java.lang.*;

public class gfg {

    public static void main(String[] args)
    {

        // char whose byte order is to be reversed
        char c1 = '\u4d00';
        char c2 = Character.reverseBytes(c1);

        // prints the reversed bytes
        System.out.println("Reversing bytes on " + c1 + " gives " + c2);
    }
}

Output:

Reversing bytes on ? gives M

Program 2:

// Java program to demonstrate the
// Character.reverseBytes() when a
// number is passed

import java.lang.*;

public class gfg {

    public static void main(String[] args)
    {

        // char whose byte order is to be reversed
        char c1 = '9';
        char c2 = Character.reverseBytes(c1);

        // prints the reversed bytes
        System.out.println("Reversing bytes on " + c1 + " gives " + c2);

        c1 = '7';
        c2 = Character.reverseBytes(c1);

        // prints the reversed bytes
        System.out.println("Reversing bytes on " + c1 + " gives " + c2);
    }
}

Output:

Reversing bytes on 9 gives ?
Reversing bytes on 7 gives ?
