在JavaFX中继续循环之前，如何等待介质结束？

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.stage.Stage;

public class MediaPlayerExample extends Application {

    @Override
    public void start(Stage primaryStage) {
        String mediaPath = "path/to/media/file.mp4";
        Media media = new Media(mediaPath);
        MediaPlayer mediaPlayer = new MediaPlayer(media);

        mediaPlayer.setOnEndOfMedia(() -> {
            // 在介质结束后执行相应的操作，例如重新播放或者继续循环
            mediaPlayer.seek(mediaPlayer.getStartTime());
            mediaPlayer.play();
        });

        mediaPlayer.play();

        StackPane root = new StackPane();
        root.getChildren().add(mediaPlayer.getMediaView());

        Scene scene = new Scene(root, 800, 600);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

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