I'm not sure what I am being asked to do?

I'm on challenge task 5 of 5 and I am a little confused by the instructions/question, I have added the following code to Messy.java:

Messy.java 
import java.util.*;

public class Messy {
    public static void main(String[] args) {
        System.out.println("one");
        System.out.println("two");
        System.out.println("four");
        System.out.println("five");


//    Please comment out this line and
        /* this line as well with a hotkey that does multi-line commenting*/
        List<String> numberWords = Arrays.asList("six", "seven", "eight", "nine");
        for (String numberWord : numberWords) {
            // Use the sout shortcut to write out numberWord;
            System.out.println(numberWord);
        }
    }
}
results.txt 
one
two
four
five
six
seven
eight
nine

In my mind this should complete the task but it keeps throwing an error message, hinting towards reformatting the code. Can anyone help?

Hi Andy Stevens

If I remember correctly, this particular challenge wants you to import Arrays and Lists specifically using two imports, instead of using one import with a wildcard. (i.e. import java.util.Arrays;). It's been a while since I've worked with Java and IntelliJ, but I feel that this was something the IDE should have "cleaned-up".

The rest looks fine. :)

Nice work. :dizzy:
