The program says i am not printing the numbers from 1 to 9, which is what my code does, can someone point the error?

About to give up on this course.

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

public class Messy {
    public static void main(String[] args) {
        List<String> numberWords = Arrays.asList("one","two","three","four","five","six", "seven", "eight", "nine","ten");
        for (String numberWord : numberWords) {
            System.out.println(numberWord);
        }
    }
}

Hey Carlos,

Your code up to Task 4 is 100% correct :thumbsup:

I copy/pasted your code into the challenge and it passed all the way to Task 4. However, it looks like you haven't pasted the proper output from the IDE to the results tab in the challenge. I somehow don't think "lol results" is what the output was in your IDE.

Once you copy/paste the proper output (as your code so far is correct) to the results.txt tab in the challenge, you probably will pass Task 5.

:dizzy:

Haha, yeah just noticed that the result tab was all empty, and that I was overthinking the whole thing. Thanks.

Well, I see that you deviated from the challenge instructions. The "System.out.println(...)" statements were completely removed! Also, ensure that you copy paste the results from the IDE's terminal window under "results.txt" tab once you are through with the challenge.

Here's a solution:

[Messy.java]

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);
        }
    }
}
