Java Program to Perform Addition Operation Using Bitwise Operators

This is the java program to perform addition of two numbers without using any arithmetic operators. The summation of two numbers can be obtained using XOR operation and carry can be obtained using AND performed at bit level.

Here is the source code of the Java Program to Perform Addition Operation Using Bit-wise Operators. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

//This is sample program to perform addition operation using bitwise operators.
import java.util.Scanner;
 
public class Bitwise_Addition 
{
    static int add(int x, int y)
    {
        int carry;
        while(y!=0)
        {
            carry = x & y;
            x = x ^ y;
            y = carry << 1;
        }
        return x;
    }
    public static void main(String args[])
    {
        Scanner input = new Scanner(System.in);
        System.out.println("Enter the numbers to be added:");
        int x = input.nextInt();
        int y = input.nextInt();
        System.out.println("The Summation is: "+add(x, y));
        input.close();
    }
}

Output:

$ javac Bitwise_Addition.java
$ java Bitwise_Addition
 
Enter the numbers to be added:
15
16
The Summation is: 31
