Still having problems reformatting code.

Okay, I've managed to reorganize my code to print out one to nine. However, I am still receiving an error. Help!

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( "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) {
            // Use the sout shortcut to write out numberWord;
            System.out.println( numberWord );
        }
    }

If you are using IntelliJ IDEA, press down CTRL+ALT+L on your keyboard. It will reformat all of your code, then paste that code into the final task + the output to pass it. The final task is most likely complaining about import java.util.* and the spaces in println and numberWords. Pressing down CTRL+ALT+L fixes that and you should pass the final task.
