java音乐播放器实现代码

本文实例为大家分享了java音乐播放器的具体代码，供大家参考，具体内容如下

这个是源码结构介绍

这个是界面，有点简陋，见笑了，但是基本上的东西都有了，没办法，没有美工的程序写的界面

直接上源代码Player.java

剩下的代码在后面附件上有，现在主要是有几个小问题，第一，我还没有找到获取音乐文件具体信息比较好的办法，所以每一首暂时还没有歌手，作曲的信息，第二界面有点难看，见谅了，第三个是打包成jar文件会有路径问题，暂时还没办法解决，我是直接在myeclipse上运行，一切正常，就是打包有点小问题

暂时先说这些了，这个是我业余时间的项目，有什么不足的，大家都可以提出来。
