# Java program to Add Subtract Multiply and Divide Two Binary Numbers

• Write a java program for addition, subtraction, multiplication and division of two binary numbers.

In this java program, we will first take two binary numbers as input from user and convert it to decimal numbers using Integer.parseInt() method. Then we add, subtract, multiply and divide integers(corresponding to given binary numbers) and convert the result back to binary number using Integer.toBinaryString() method.

## Java program to add subtract multiply and divide binary numbers

```package com.tcc.java.programs;

import java.util.Scanner;

/**
* Java Program for Binary number addition, subtraction, multiplication and
* division
*/
public class BinaryArithmetics {
public static void main(String[] args) {
String bOne, bTwo;
int iOne, iTwo;
Scanner scanner = new Scanner(System.in);

System.out.println("Enter First Binary Number");
bOne = scanner.next();

System.out.println("Enter Second Binary Number");
bTwo = scanner.next();
// Convert Binary numbers to decimal
iOne = Integer.parseInt(bOne, 2);
iTwo = Integer.parseInt(bTwo, 2);

System.out.println("Sum = " + Integer.toBinaryString(iOne + iTwo));
System.out.println("Difference = " + Integer.toBinaryString(iOne - iTwo));
System.out.println("Product = " + Integer.toBinaryString(iOne * iTwo));
System.out.println("Quotient = " + Integer.toBinaryString(iOne / iTwo));
}
}
```
Output
```Enter First Binary Number
1000
Enter Second Binary Number
1000
Sum = 10000
Difference = 0
Product = 1000000
Quotient = 1
```
