It is saying the results are wrong

Messy.java
import java.util.*;

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(numberWord); // Now implemented
        }
    }
}

I see a few issues:

  1. the reformatting should have replaced the wildcard import with two discreet ones:
    ā€ƒ import java.util.Arrays;
    ā€ƒ import java.util.List;
  2. the instructions say to "re-arrange the lines in order", but this program is still writing out the original unordered sequence: "five - one - six - etc." You'll need to fix that "using a combination of adding, deleting and moving lines".
  3. there is still a missing number and a duplicated number
  4. finally, the output pasted into results.txt don't match what the program actually produces.
