Bummer: Are you sure you ran the reformat code action? This seems suspect: import java.util.*

The reformat should have converted the line with the wildcard into two discreet imports:

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

Also, the instructions say "Make sure you run the code and that it counts from one through nine correctly.". But your output has two "six" lines.

And finally, it looks like the final instruction text got into the code area.

Why is it necessary to have written down Arrays and List? What's wrong with * ? I feel like the course is making it feel like a bad thing.

You have repeat six twice. My soln is :

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

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

import java.util.Set; import java.lang.Iterable;

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

  }
}
}
