Eclipse trouble - getting standalone file to run in project

I've always despised having to create a project in order to run a single Java file, which apparently I have to do in Eclipse. I finally figured out how to add a file to my project, but once I do that and I try to run the file, I get the following error: Editor does not contain a main type

What am I doing wrong? What all do I need to do to get an existing .java file to compile and run in Eclipse (apparently I have to add it to a project, which I now know how to do)?

One of these [answers](http://stackoverflow.com/questions/1113729/editor-does-not-contain-a-main-type) should work for you. – Siddhartha Oct 18 '15 at 00:20
Thanks for the link. I tried opening and closing the project like several people there suggested, and am now getting a different error: Selection does not contain a main type – NickH88 Oct 18 '15 at 00:47
Hmm. Does the class you're trying to run have a main method like ```public static void main(String[] args) {```? Which you're running as the Java application. – Siddhartha Oct 18 '15 at 00:48
Yes, it does have a main method. – NickH88 Oct 18 '15 at 01:39
Try [this?](http://stackoverflow.com/a/6757677/792238) – Siddhartha Oct 18 '15 at 02:30
That worked! Thanks! – NickH88 Oct 18 '15 at 03:46
