Close JavaFX window from a static method without arguments

I have an abstract class which I use for opening other windows. Now I want this class to be able to close the window I invoke it's methods from. Is it even possible to do?

Here's a small example, so you would get easier acknowledged with what i mean:
Window.java

public abstract class Window{
    public static void closeWindow(){ ... }
}

MainController.java

public class MainController extends Window implements Initializable {
    @Override
    public void initializable (URL blablabla, ResourceBundle blablabla){
        closeWindow();
    }
}
