Question

我在Java IDE Eclipse中开发并运行了此代码。这是我为Main类开发的代码：

package application;

import com.sun.prism.paint.Color;



import javafx.application.Application;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;


public class Main extends Application {
@Override
public void start(Stage primaryStage) {

    Player player=new Player("file:///C:/getg.mp4");
    Scene scene=new Scene(player, 750, 480);
    primaryStage.setScene(scene);
    primaryStage.show();




}

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

}

这是我为Player类开发的代码：包裹申请;

import javafx.scene.layout.BorderPane;

import javafx.scene.layout.Pane;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.scene.media.MediaView;

public class Player extends BorderPane {    
    Media media;
    MediaPlayer player;
    MediaView view;
    Pane mpane;
    public Player(String file){
        media=new Media(file);
        player=new MediaPlayer(media);
        view =new MediaView(player);
        mpane=new Pane();

        mpane.getChildren().add(view);
        setCenter(mpane);

        player.play();


    }

}

这是我生成的错误：

我安装了Java Effects，你觉得怎么回事？

媒体播放有问题，我用Java开发
