Question

我正在尝试播放一些小的音效，我通过加载剪辑，播放它的方法来做这个，然后关闭剪辑以允许稍后加载新的剪辑导致任何LineUnavailable问题。这是我使用的方法：

public void playClip(String filename){

    Clip clip = null;

    try{

        AudioInputStream inputStream = AudioSystem.getAudioInputStream(getClass().getResource(filename));
        AudioFormat format = inputStream.getFormat();
        DataLine.Info info = new DataLine.Info(Clip.class, format);
        clip = (Clip)AudioSystem.getLine(info);
        clip.open(inputStream);
        clip.start();

    }catch(Exception e){

        e.printStackTrace();

    }

}

现在，在clip.start()之后，剪辑只是停留在一个地方，用完了一行，直到我收到以下错误：

javax.sound.sampled.LineUnavailableException: line with format PCM_SIGNED 44100.0 Hz, 16 bit, stereo, 4 bytes/frame, little-endian not supported.

剪辑结束后如何添加clip.close()？

Answer 1

尝试添加finally块以关闭连接
