Java Exercises: Add two numbers without using any arithmetic operators

Java Basic: Exercise-111 with Solution

Write a Java program to add two numbers without using any arithmetic operators.

Given x = 10 and y = 12; result = 22

Sample Solution:

Java Code:

import java.util.Scanner;
public class Example111 {
     public static void main(String[] arg) 
	 {
	   int x, y ;
	   Scanner in = new Scanner(System.in);	
	   System.out.print("Input first number: ");
	   x = in.nextInt(); 
	   System.out.print("Input second number: ");
	   y = in.nextInt(); 
      while(y != 0){
            int carry = x & y;
            x = x ^ y;
            y = carry << 1;
        }
        System.out.print("Sum: "+x); 
		System.out.print("\n");     	
	}	
}

Sample Output:

Input first number: 10                                                  
Input second number: 12                                                
Sum: 22
