I can't run Messy.java

When I want to run my file Messy.java I get a window "Edit Configurations" and the program doesn't run. What's wrong?

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");
        System.out.println("six");
        System.out.println("seven");
        System.out.println("eight");
        System.out.println("nine");

/*        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");
        }
    }
}

It was named "Messy" I don't know why because I chose it to be java file. When I renamed it to be "Messy.java" everything works, but the file looks like a text file, not java file.

I think you are using Intellij, and if so, try to right click anywhere in the class 'Messy.java' and click on the "Run 'Messy.main()'".

I did it and I got an error: " class Messy is public, should be declared in a file named Messy.java".

Is your file named Messy.java?
