I am receiving a compiler error :(

I am receiving a "cannot find symbol" error due to the reformat of code in IntelliJ. If I add import java.util.*, the compiler error disappears but I can't pass the challenge. If I change ArrayList<String> numberWords; to List<String> numberWords;, I still receive the same error.

```public class Messy {

public static void main(String[] args) {

ArrayList<String> numberWords; /* Please comment out this line and this line as well with a hotkey that does multi-line commenting*/

    numberWords = Arrays.asList("six", "seven", "eight", "nine");
    for (String numberWord : numberWords) {
        System.out.println("one");
        System.out.println("two");
        System.out.println("three");
        System.out.println("four");
        System.out.println("five");
        System.out.println("six");


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

}```

Messy.java 
public class Messy {

    public static void main(String[] args) {
ArrayList<String> numberWords;
              /*  Please comment out this line and
                this line as well with a hotkey that does multi-line commenting*/

        numberWords = Arrays.asList("six", "seven", "eight", "nine");
        for (String numberWord : numberWords) {
            System.out.println("one");
            System.out.println("two");
            System.out.println("three");
            System.out.println("four");
            System.out.println("five");
            System.out.println("six");


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

I figured it out. I had to use the Intention Action and change to import.java.Arrays and import.java.List to pass. The code reformatter did not change it from the import.java.utils as I believe it was expected to do.
