I think the actual solution may like this:
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int harry, larry, max;

        while(sc.hasNext()){
            harry = sc.nextInt();
            larry = sc.nextInt();

            max = harry + larry;

            if(((max % 10) != 0)){

                if(((max % 10) <= ((max / 10)))){
                    max = (10 * ((max / 10)));
                }
                else{
                    max = (10 * ((max / 10) + 1));
                }
            }
            System.out.println((max - harry) +" "+ (max - larry));
        }
        sc.close();
    }

}
