使JavaFX应用程序变为非静态

Question

I know that's maybe noob question and lot of others can find it useless, but I would be glad if someone could help me.

In every tutorial I saw making applications in JavaFX static like so:

public class TestingApp extends Application
{

    @Override
    public void start( Stage primaryStage )
    {
        ...
    }

    public static void main( String[] args )
    {
        launch( args );
    }
}

but is there some way to define it non-static like so?:

public class TestingApp extends Application
{

    @Override
    public void start( Stage primaryStage )
    {
        ...
    }

    public TestingApp() {}

}

public class Main
{

    public static void main( String[] args )
    {
        TestingApp ta1 = new TestingApp()
        TestingApp ta2 = new TestingApp()

        ta1.launch( args )
        ta2.launch( args )
    }

}

I already saw this: Starting a second JavaFX Application , but it doesn't solve my problem.

Per JVM instance you can only have one JavaFX application and one JavaFX application thread running.

But you can create multiple Stages (windows), if that is what you're looking for. The primary stage is provided by the start method but you can create secondary stages yourself.
