for writing output in a text file

I really don't know where is the problem, please help me.

Messy.java
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.PrintStream;
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) {
            System.out.println(numberWord);
            // Use the sout shortcut to write out numberWord;
        }
        try {
            PrintStream out = new PrintStream(new FileOutputStream(
                    "results.txt"));
            System.setOut(out);
        }

        catch (FileNotFoundException e) {
            e.printStackTrace();
        }

    }
}

You don't need to write text-file by Java, Just copy and paste your result from IntelliJ Idea console to 'results.txt' tab.

My guess is that you are calling the code that sets the standard output to a file after writing to standard output. Try the following:

try {
    PrintStream out = new PrintStream(new FileOutputStream("results.txt"));
    System.setOut(out);
}
catch (FileNotFoundException e) {
     e.printStackTrace();
 }

for (String numberWord : numberWords) {
      System.out.println(numberWord);
}

Thank you , but I still can't passe the test, It says the results don't appear to be counting properly,check you have one though nine in order
