import java.util.Scanner;

public class Test {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        try {
            System.out.print("Enter an integer: ");

            int m = in.nextInt();
            System.out.print("Enter another integer: ");

            int n = in.nextInt();
            System.out.println(m + " " + n);
        } catch (Exception e) {
            System.out.println("Invalid input.");
        }
    }
