如何使用 JavaFX 播放声音
我刚刚开始使用JavaFX。我知道它的基本原理。我试图使用媒体和mediaplayer类来播放一种声音,称为“声音.mp3”。我正在用eclipse编程,我在src文件夹中有声音文件,与“(默认包)”文件夹相同。这是我的代码:
import javafx.scene.media.*;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class Main extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
primaryStage.setTitle("Hello World!");
String ssound = "sound.mp3";
Media sound = new Media(ssound);
MediaPlayer mediaPlayer = new MediaPlayer(sound);
mediaPlayer.play();
StackPane root = new StackPane();
primaryStage.setScene(new Scene(root, 800, 450));
primaryStage.show();
}
}
请告诉我我做错了什么。
以下是来自控制台的错误消息:
