Clean up this mess

Hey there,

On the "Clean up this mess" challenge I'm copying and pasting this code (which compiles and runs correcty)

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);
        }
    }
}

But I keep getting this error.

./Messy.java:8: error: ';' expected Please comment out this line and

I've tried doing single line comment, removing the whole lines and nothing seems to work and can't make any progress. Any tips?

Cheers, Luis

Hi Luis,

I have tried your code and it runs perfect in IntellyJ. Only thing I had to change were the imports ...

The compiler was complaining about this line:

import java.util.*;

So I changed it to:

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

Using the alt enter command (Mac)

Hi Gregorij,

Thanks for your reply. I just tried that and keep getting the same error.

Cheers, Luis

Away from my computer now, but try giving space between the star and your comments on both sides. Never seen that before...but might work.

Thanks Craig. It didn't make any difference. Probably this is silly, but I just can't use the multi-line comment key shortcut because my keyboard is Spanish configured. Do you think the drill can tell from that?

Cheers, Luis

Will they allow you to use // to comment out each line individually?

Hi Robert,

Thanks for your reply. Unfortunately not. I've even introduced some other obvious syntax errors and still stuck on the same one. I wonder if there could be any bug on the Challenge app.

Cheers, Luis
