"Selection does not contain any Java files" from eclipse

Below my Test.java which is one .java file from a student project. I don't see why eclipse gives me " Selection does not contain any Java files " error when I tried to "run" it from the menu Run-->Run ? Could you explain why?

This post Java launch error selection does not contain a main type does not explain my problem. In my case "main" is well defined. 

class Test {
   public static void main(String[] args) {
      test1();
   }

   static void test1() {
      Font f = new Font("SansSerif", Font.PLAIN, 70);
      Glyph g = new Glyph(f, 'g');
      System.out.println(g);
   }
}

The problem is that the file isn't in a source folder. So for Eclipse, it's just a text file which (by coincidence) contains some Java code. But since the compiler never saw it, there is no .class file -> Eclipse can't run it.

Create a source folder (New... -> Source Folder) or move the file into an existing source folder in your project (they contain a little "package" symbol in the icon) and try again.

Haven't used eclipse in some time now as I use InteliJ but make sure you edit configurations and select your main file so Run can then execute your app.

The name of the file and the name of the class should match. That is the reason, it's not able to recognize it. Please check the name again.
