1、在小程序中播放声音
java可以播放au,aiff,wav,midi,rfm格式的音频
可以调用Applet的一个静态方法：
newAudioClip(URL url,String name) url是地址，name是音频名称
也可以用Applet类的实例方法：
getAudioClip(URL url,String name)
根据url地址和声音文件name，获得一个用于播放的音频对象，这对象可以使用下面的方法来处理声音：
play() 播放声音文件name
loop() 循环播放name
stop() 停止播放name
2、Java媒体框架(JMF)
创建播放器
try
{
URL url=new URL(getDocumenBase(),视频文件名称);
player player=Manager.createPlayer(url);
}
catch(IOException e){}
向播放器注册控制监视器
player.addControllerListener(监视器);
创建监视器必须使用接口ControllerListener ，该接口中的方法是
public void controllerUpdate(ControllerEvent e)
让播放器对媒体进行预提取
player.prefetch()
启动播放器
player.start();
停止播放器
player.stop();
停止播放器后必须释放内存中的资源
player.deallocate();
