predict the output:

import java.util.*;

public class first {
    public static void main(String arg[]) {
        int num1, num2, sum;
        Scanner a = new Scanner(System.in);

        System.out.println("enter the numbers");
        num1 = a.nextInt();
        num2 = a.nextInt();
        sum = num1 + num2;
        System.out.println(sum);

    }

}
