I'm using JavaFx 11 with OpenJDK 15. I've watched many sample videos but still getting the errors.

Is that the problem of configuration? My music file is in the same folder of src. Can anyone help? Thanks!

This is my source code.


    import MonopolyRPG.Controller.GameModePage;
    import javafx.application.Application;
    
    import javafx.scene.media.MediaPlayer;
    import javafx.stage.Stage;
    
    import javafx.scene.media.Media;
    
    
    public class Main extends Application {
    
        public static void main(String[] args) {
            Application.launch();
        }
    
        @Override
        public void start(Stage primaryStage) throws Exception {
            music();
            GameModePage gameModePage=  new GameModePage();
            gameModePage.start();
            primaryStage.close();
        }
    
        MediaPlayer mediaPlayer;
    
        public void music() {
            String filepath="file:///E:/MonopolyRPG-master/BGM.mp3";
            Media sound = new Media(filepath);
            //MediaPlayer mediaPlayer = new MediaPlayer(sound);
            mediaPlayer = new MediaPlayer(sound);
            mediaPlayer.setAutoPlay(true);
        }
    
    }

The errors keep occurs. And I tried to configure VM option and change .wav file to .mp3, still can't realise what happened.

Is this the correct syntax?
