Java : Program to swap two number without using any arithmetic operator

import java.util.Scanner;

/*
 * 
 * Swap two number without using any arithmetic operator like + , - etc

 * we can achieve the solution using the XOR operator
 */

/* output
 Enter number A : 
10
Enter number B : 
30
Number before swapped A and B respectively  --> 10   30
Number after swapped A and B respectively  -->  30   10
