Question

我对使用Java播放声音有一些疑问，希望你能帮帮我 1.如何通过＆＃34; Stop＆＃34;停止播放声音？按钮？
2.如何减慢（或冷却时间）声音？
3.我想创建一个选项框架，我可以调整音量和静音选项，我该怎么做？这是我的代码：

    private void BGM() {
        try {
            File file = new File(AppPath + "\\src\\BGM.wav");
            Clip clip = AudioSystem.getClip();
            clip.open(AudioSystem.getAudioInputStream(file));
            clip.start();
        } catch (Exception e) {
            System.err.println(e.getMessage());
        }
    }

任何帮助将不胜感激，并祝你有愉快的一天！

您正在使用面向对象的编程语言，所以让我们利用它并将剪辑/音频的管理封装到一个简单的类中......

    System.setProperty("javax.net.ssl.trustStore", trustStorePath);//The path to the trust store file
    System.setProperty("javax.net.ssl.trustStorePassword", trustStorePassword);//The trust store password
    try(SSLServerSocket socket = (SSLServerSocket) SSLServerSocketFactory.getDefault().createServerSocket(ssl_listen_port)) {
        socket.setReuseAddress(true);
        System.out.println("\tServer SSL socket created on port " + ssl_listen_port);
        while(serverActive) {
            //Omitted multithreading code for read-ability:
            final SSLSocket s = (SSLSocket) socket.accept();
            try {
                s.startHandshake();
            } catch(SSLHandshakeException e) {
                System.err.println("Failed to initialize SSL handshake: " + e.getMessage());
                continue;               
            }

            //(The server then handles the remainder of the request as if it were http.)
        }
    } catch(BindException e) {
        System.err.println(" /!\\\tUnable to bind to ssl port " + ssl_listen_port + ":\r\n/___\\\t" + e.getMessage());
    } catch(Throwable e) {
        e.printStackTrace();
    }

现在，要使用它，您需要创建一个类实例字段，它允许您从要使用它的类中的任何位置访问该值...

public class AudioPlayer {

    private Clip clip;

    public AudioPlayer(URL url) throws IOException, LineUnavailableException, UnsupportedAudioFileException {
        clip = AudioSystem.getClip();
        clip.open(AudioSystem.getAudioInputStream(url.openStream()));
    }

    public boolean isPlaying() {
        return clip != null && clip.isRunning();
    }

    public void play() {
        if (clip != null && !clip.isRunning()) {
            clip.start();
        }
    }

    public void stop() {
        if (clip != null && clip.isRunning()) {
            clip.stop();
        }
    }

    public void dispose() {
        try {
            clip.close();
        } finally {
            clip = null;
        }
    }

}

然后，当您需要它时，您创建一个private AudioPlayer bgmPlayer;的实例并将其分配给此变量

AudioPlayer

现在，您需要时，只需拨打try { bgmPlayer = new AudioPlayer(getClass().getResource("/BGM.wav")); } catch (IOException | LineUnavailableException | UnsupportedAudioFileException ex) { ex.printStackTrace(); }或bgmPlayer.play()

即可
