I want to run a specific .java file (a class), but Eclipse is not co-operating.

I have tried to follow the instructions here --> eclipse how to run a different class

... but my "Run As" menu item never contains "Java Project".

I have tried accessing the menu after right-clicking in the .java pane and tab itself, and from the .java name and class name in the Package Explorer, but of course that doesn't make a difference. The only option I ever get is "Run Configurations".

(and yes, my .java has a "main" method.)

import com.jsyn.JSyn;

public class SuperSimpleSounds {

    public static void main() {

[...]

What, exactly, is needed to be able to run an individual class (an individual .java file)?

java eclipse
