文章比较长，请耐心看完。
一、整体框架
该程序由四个类组成，GameFrame类（程序主体）、Map类（地图基础设置）、MapFactory类（地图构图）、Sound类（添加音乐），下面是程序结构图。
注意音乐格式要转MIDI序列（直接改文件后缀名不可行，如果想更换背景音乐，建议下载widi进行格式转换）
二、游戏效果图
游戏画面没有设置的很炫酷，因为绿色比较护眼。
正在看这篇博客的你，让眼睛休息一下吧！

言归正传，我们来看游戏代码
代码直接复制粘贴就能运行（素材包放在项目src目录下）

四、游戏分析
游戏操作
键盘上下左右键控制人物的移动，按A回到上一关，按D直接进入下一关。
数组解读
很多人对这个庞大的数组很好奇，其实呢，它们非常简单，下面我来解读一下。
0（墙外的空余区域）；1（墙）；2（箱子）；3（箱子位于目标点上）；
4（目标点）；5（人物向下）；9（空地）；
五、wav格式音乐代码
由于mid格式比较少见，一般的软件无法实现该格式的转换，所以我们使用javax.sound实现简单的音频播放（只支持AU，RA，WAV格式），相比而言比较大众化。可以自己挑选喜欢的音乐作为背景音乐。
更新后代码如下（只修改GameFrame类和Sound类）
