clean up this mess

Guys did you face this problem, i pasted the code correctly. but it is saying " bummer did you reformat the code" suspect on import java.util.*

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);
        }
    }
}

Try expanding java.util.* to single imports

Thank that one worked. However may I get help on the Refactoring challenge. What are required to do. Is it that when we use the rename Refactoring for the mSongQueue to mSongRequestQueue, are we supposed to do the Refactoring the Song to SongRequest as u demonstrated on the video???

Also as I was experimenting, I tried to Refactoring the song to SongRequest following the video tutorial but was failing to do so, I was getting an error that "field type is not valid"

Hi Smart!

Yes follow the video and then do the last bit of refactoring as required by the challenge. If you are still experiencing problems, please add a new forum question on that video...so others can learn too!

Thanks!
