    Using stream

    import java.util.*;
import java.util.stream.*;

public class Solution {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        IntStream.iterate(1, n -> n + 1)
                 .takeWhile(n -> sc.hasNextLine())
                 .forEach(n -> System.out.println(n + " " + sc.nextLine()));
        sc.close();
    }
}
