Java program to add two binary numbers.

CODE:

import java.util.Scanner;

class prac2A

{

public static void main(String[] args)

{

long binary1, binary2;

int i = 0, remainder = 0;

int[] sum = new int[20];

Scanner in = new Scanner(System.in);

System.out.print("Input first binary number: ");

binary1 = in.nextLong();

System.out.print("Input second binary number: ");

binary2 = in.nextLong();

while (binary1 != 0 || binary2 != 0)

{

sum[i++] = (int)((binary1 % 10 + binary2 % 10 + remainder) % 2);

remainder = (int)((binary1 % 10 + binary2 % 10 + remainder) / 2);

binary1 = binary1 / 10;

binary2 = binary2 / 10;

}

if (remainder != 0)

{

sum[i++] = remainder;

}

--i;

System.out.print("Sum of two binary numbers: ");

while (i >= 0)

{

System.out.print(sum[i--]);

}

System.out.print("\n");

}

}
