jdk17使用java写一个多个MP3合成一个 的代码

在Java中，使用JDK17和JavaFX库可以创建一个简单的音频文件合并工具。这里是一个基本的示例，它使用了`javafx.scene.media.MediaPlayer`来播放MP3文件并进行合并：

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

import java.io.File;
import java.util.ArrayList;

public class MP3Merger extends Application {

    private ArrayList<MediaPlayer> mediaPlayerList = new ArrayList<>();
    private int currentTrackIndex = 0;

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

    @Override
    public void start(Stage primaryStage) {
        Button playButton = new Button("Play");
        playButton.setOnAction(event -> {
            if (mediaPlayerList.get(currentTrackIndex).getStatus() != MediaPlayer.Status.STOPPED) {
                mediaPlayerList.get(currentTrackIndex).pause();
            } else {
                mediaPlayerList.get(currentTrackIndex).play();
            }
        });

        StackPane root = new StackPane();
        root.getChildren().add(playButton);

        Scene scene = new Scene(root, 300, 250);

        File mp31 = new File("path_to_your_first_mp3.mp3"); // 替换为第一个MP3路径
        Media media1 = new Media(mp31.toURI().toString());
        mediaPlayerList.add(new MediaPlayer(media1));

        // 添加更多MP3，按照这种方式添加到列表
        // ...
        
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public void addTrack(File mp3File) {
        Media media = new Media(mp3File.toURI().toString());
        mediaPlayerList.add(new MediaPlayer(media));
    }

    public void stopAllTracks() {
        for (MediaPlayer mediaPlayer : mediaPlayerList) {
            mediaPlayer.stop();
        }
        mediaPlayerList.clear();
        currentTrackIndex = 0;
    }

    public void nextTrack() {
        if (currentTrackIndex < mediaPlayerList.size() - 1) {
            currentTrackIndex++;
        } else {
            System.out.println("No more tracks to play.");
        }
    }

    public void previousTrack() {
        if (currentTrackIndex > 0) {
            currentTrackIndex--;
        } else {
            System.out.println("Already at the first track.");
        }
    }
}
