Hack: Binary Add

public class BinaryAdd {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.print("Enter first binary number: ");
        // Use a radix of 2 cuz input is binary
        String input1 = sc.nextLine();   
        int a = Integer.parseInt(input1, 2);
        System.out.println(input1);

        System.out.print("Enter second binary number: ");
        String input2 = sc.nextLine();
        int b = Integer.parseInt(input2, 2);
        System.out.println(input2);

        int sum = a + b;
        System.out.println("Sum of two binary numbers is: " + Integer.toBinaryString(sum));
    }
}

BinaryAdd.main(null);

Enter first binary number: 10
Enter second binary number: 10
Sum of two binary numbers is: 100
