        Scene scene = new Scene(root, 400, 300);
        primaryStage.setTitle("Hello World!");
        primaryStage.setScene(scene);
        primaryStage.show();
     * The main() method is ignored in correctly deployed JavaFX application.
     * main() serves only as fallback in case the application can not be
     * launched through deployment artifacts, e.g., in IDEs with limited FX
     * support. NetBeans ignores main().
     * @param args the command line arguments
    public static void main(String[] args) {
        launch(args);
}I really tried to do something very simple but seems no !!
And by the way, the pause button, when i press on it, it should only pauses the play but seems it's making the player stop not pause ^^

Answer 1

As for the Mp3 Player, here is the code, would be nice of to see if there is something that can be added, perfectionized !!
