title: Java Program to Add two Binary Numbers
shortTitle: Add two Binary Numbers
description: In this tutorial we will write a java program to add two binary numbers.
---

Binary number system has only two symbols **0** & **1** so a **binary numbers** consists of only 0’s and 1’s. Before we write a program for addition, lets see how we do the addition on paper, this is shown in the diagram below:
![Addition of two binary numbers](https://via.placeholder.com/800x500.webp?text=Addition+of+two+binary+numbers)

## Adding binary numbers in Java

### Code:

```java
import java.util.Scanner;
public class JavaExample {
public static void main(String[] args)
{
//Two variables to hold two input binary numbers
long b1, b2;
int i = 0, carry = 0;

//This is to hold the output binary number
int[] sum = new int[10];

//To read the input binary numbers entered by user
Scanner scanner = new Scanner(System.in);

//getting first binary number from user
System.out.print("Enter first binary number: ");
b1 = scanner.nextLong();
//getting second binary number from user
System.out.print("Enter second binary number: ");
b2 = scanner.nextLong();

//closing scanner after use to avoid memory leak
scanner.close();
while (b1 != 0 || b2 != 0)
{
sum[i++] = (int)((b1 % 10 + b2 % 10 + carry) % 2);
carry = (int)((b1 % 10 + b2 % 10 + carry) / 2);
b1 = b1 / 10;
b2 = b2 / 10;
}
if (carry != 0) {
sum[i++] = carry;
}
--i;
System.out.print("Output: ");
while (i >= 0) {
System.out.print(sum[i--]);
}
System.out.print("\n");
}
}
```
### Output:

```text
Enter first binary number: 11100
Enter second binary number: 10101
Output: 110001
```
