Your code should look like this when you are done:

import java.util.*;

public class Messy {

    public static void main(String[] args){
       System.out.println("one");
       System.out.println("five");
       System.out.println("six");
       System.out.println("four");     
       System.out.println("two");
       //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) {
         System.out.println(numberWord);
         // Use the sout shortcut to write out numberWord;
       }
    }
}

I believe that the challenge wants you to use a multi-line comment for the two comments:

/*
  *Please comment out this line and 
  *this line as well with a hotkey that does multi-line commenting
*/
