我用过Applet.newAudioClip(URL)但是只能得到一个音乐文件 我要同时用几个这样的语句时 只有第一个音乐能打开 请大家指点一下错误。 谢谢！万分感激！！！

斑竹您说的我有点没明白我想问的问题是getAudioClip()在这里怎么得不到音乐资源，还有我用过Applet.newAudioClip()这个静态方法得到资源，但是如果我要得到两首音乐的资源，第二首怎么也得不到
如Applet.newAudioClip(url1);Applet.newAudioClip(url2);在播放第二个的时候就回出现异常，请大家辛苦一下，指点一下，后告诉我个别的方法。谢谢！！！万分感激！！！

对不起 昨天说错了 没有异常 是什么都不发生 就是不能播放两个音乐文件 谁在上面就能播放谁，下面的就不能放 而且没任何反映，由于上网不是很方便 现在才贴出来 希望斑竹和大家帮帮我 谢谢大家！ 感谢斑竹的回答！
