Now finally after running your code, please paste it in the Messy.java file and the results from the console in the resu

I am lost on this and need help?

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) {
      // Use the sout shortcut to write out numberWord;
      }

You haven't done any of the suggested refactoring, or commented out a couple lines (That aren't legal java). The point of the exercise is to learn the IDE. The results.txt is meant to be a series of numbers. The java is meant to look something like the following (your IDE probably has better automatic style than I do).

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);
    }
  }
}

You can copy this, or just use it as a guide to the steps to take within your IDE. Up to you.

The answer is : First, you need to sort the system out print one two three four by the command in windows ctrl+shift* + arrow **up or down . Thereafter you need to compile, copy the result and paste on the text file.

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);
        }
    }
}
