Answer 1

public void playGoSound(){
//文件流的操作如果文件或路径不存在，则执行异常处理
try {
// 文件路径
FileInputStream goFis = new FileInputStream(userDir + "go.wav") ;
//音频流定义
AudioStream goAudioStream = new AudioStream(goFis) ;
//调用AudioPlayer，开始播放文件
AudioPlayer.player.start(goAudioStream);
//播放完成后，线程暂停10ms
Thread.sleep(10) ;
//关闭音频流
goAudioStream.close() ;
}
//文件不存在似的处理
catch (FileNotFoundException e) {
//打印错误信息
e.printStackTrace();
}
//输入输出异常处理
catch (IOException e) {
e.printStackTrace();
}
//这是线程休眠时，打断线程执行的异常处理
catch (InterruptedException e) {
e.printStackTrace();
}
}
private class BackMusic implements Runnable{
public void run() {
playBackSound() ;
}
