So there are basically five steps.

  1. copy paste the code in Messy.java to you IDE
  2. reformat the code (IMPORTANT: make sure that within your IDE this also optimizes imports!)
  3. Comment out the lines using: Ctrl + / or Command + / (in macOS)
  4. Change the order of the System.out.println() statements so that they print out: one two three four five. Then add a System.out.println() statement within the for loop which prints out numberWord using a shortcutyou can do this by first typing sout and then pressing the tab key.
  5. Run your program, copy paste the output only to results.txt then copy paste the code in Messy.java. Submit the code and you are done!

I recommend you try the above again. If you don't feel like it, understand the steps. Here's the correct code:

import java.util.Arrays;
import java.util.List;

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

result:

one
two
three
four
five
six
seven
eight
nine
