如何在退出JFrame时停止AudioSystem？

import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.UnsupportedAudioFileException;
import javax.swing.JFrame;
import javax.swing.WindowConstants;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.io.IOException;

public class AudioStopExample extends JFrame {

    public AudioStopExample() {
        // 设置窗口标题和大小
        setTitle("Audio Stop Example");
        setSize(300, 200);

        // 添加窗口关闭事件监听器
        addWindowListener(new WindowAdapter() {
            @Override
            public void windowClosing(WindowEvent e) {
                stopAudio();
                System.exit(0);
            }
        });

        // 设置窗口关闭操作
        setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    }

    private void stopAudio() {
        try {
            // 停止所有正在播放的音频线
            AudioSystem.lineFlush();
        } catch (IOException | UnsupportedAudioFileException | LineUnavailableException e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        AudioStopExample frame = new AudioStopExample();
        frame.setVisible(true);
    }
}
