Java Example to sum of two integer using Bitwise operator

Java Example to sum of two integer using Bitwise operator

In this article, we will discuss the concept of the Java Example to sum of two integers using Bitwise operator.

In this post, we are going to learn how to  write a program to find the sum of two numbers using Bitwise operator in Java programming language

Code to find the sum of  two numbers 

Sum of two integer using Bitwise operator

The program allows the user to enter two integers and then calculates the sum of given  numbers using  Bitwise operator in Java language

Program 1

//subtract two integer numbers using bitwise in Java
import java.util.*;
public class SubtractNumBitwise{
public static void main(String args[]){
    int x,y;//variable declaration
    Scanner sc=new Scanner(System.in);
    //scanner class for input
System.out.println("Please Enter the first integer number ");
int num1=sc.nextInt();//ask input from the user and store the input in num1
System.out.println("Please Enter the second integer number ");
int num2=sc.nextInt();//ask input from the user and store the input in num2
x=num1;//Assign the value of num1 to a
y=num2;//Assign the value of num2 to b
while(num2!=0){//Calculate sum of given numbers using bitwise operator
    int brw =num1&num2;
    num1=num1^num2;
    num2=brw<<1;
}
System.out.println("Sum of two numbers "+x+" and "+y+" is: "+num1);
//Display output on the screen
}
}

When the above code is executed, it produces the following result

Please Enter the first integer number
250
Please Enter the second integer number
120
Sum of two numbers 250 and 120 is: 370

 

Sum of two integer using Bitwise operator – with Method

The program allows the user to enter two integers and then calculates the sum of given  numbers using  Bitwise operator in Java language.

Program 2

//sum of two integer numbers using bitwise in Java
import java.util.*;
public class SumNumBitwiseMethod{
public static void main(String args[]){
    int x,y;//variable declaration
    Scanner sc=new Scanner(System.in);
    //scanner class for input
System.out.println("Please Enter the first integer number ");
int num1=sc.nextInt();//get input from user for num1
System.out.println("Please Enter the second integer number ");
int num2=sc.nextInt();//get input from user for num1
x=num1;//Assign the value of num1 to x
y=num2;//Assign the value of num2 to y
subNum(num1,num2);//Calling the method with argument
}
static void subNum(int num1,int num2){//method definition with parameter
while(num2!=0){//calculate sum of two numbers using bitwise operator
    int brw =num1&num2;
    num1=num1^num2;
    num2=brw<<1;
    
}
System.out.println("Sum of two numbers is: "+num1);
//display output on the screen

}
}

When the above code is executed, it produces the following result

Please Enter the first integer number
1250
Please Enter the second integer number
1500
Sum of two numbers 1250 and 1500 is: 2750
