    public AePlayWave(String name) {
        this.name = name;
    }

    @Override
    public void run() {
        File file = new File(name);
        AudioInputStream audioInputStream = null;
        try {
            audioInputStream = AudioSystem.getAudioInputStream(file);
        } catch (Exception e) {
            e.printStackTrace();
            return;
        }

        AudioFormat format = audioInputStream.getFormat();
        SourceDataLine auline = null;
        DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);

        try {
            auline = (SourceDataLine) AudioSystem.getLine(info);
            auline.open(format);
        } catch (Exception e) {
            e.printStackTrace();
            return;
        }

        auline.start();
        int nBytesRead = 0;
        byte[] abbytes = new byte[512];
        try {
            while ((nBytesRead = audioInputStream.read(abbytes, 0, abbytes.length)) != -1) {
                if (nBytesRead >= 0) {
                    auline.write(abbytes, 0, nBytesRead);
                }
            }

        } catch (Exception e) {
            e.printStackTrace();
            return;
        } finally {
            auline.drain();
