一．实验目的和要求深入了解图形用户界面基本组件窗口、按钮、文本框、选择框、滚动条等的使用方法，了解如何使用布局管理器对组件进行管理，以及如何使用 Java 的事件处理机制。
将所学知识进行综合运用，模仿设计具有实际意义的应用程序。
锻炼使用新类（没有介绍的）类的能力。
二、实验原理分析 test.java：主类。MapConfig.java: 素材图片定义、整合接口GetLevelDialog.java： 选关类继承JDilog类，采用弹出模态对话框，同时构建选关的按钮、确定、取消等并且给出地图打不开的提示Utils.java：工具类用于游戏主体判断是否存在地图文件UpdateThread.java：刷线面板类，继承Thread。每0.01秒刷新面板一次。其中10为10ms（毫秒）MainGame.java：游戏主体类继承JFrame同时实现MapConfig接口 游戏面板：创建JPanel对象panel组建面板并且添加标题、菜单、选关按钮。定义GetMAp（）方法,使用try{}catch来读取放在D盘推箱子文件夹内的地图自定义内部游戏面板类MyPanel并且继承JPanel，通过数组的下标来确定图片的位置，通过GetGameImage方法获取对应数字的图片定义内部游戏按键监听类PanelListenner继承KeyAdapter，同时定义Move()方法以0墙 1地板 2空箱子 3 箱子 4箱子点 5出生点（人物所在位置）为基础通过监听用户的按键改变对应的playerx的值并且定义check()方法来进行碰撞检测，通过检查角色所在位置周围的坐标数组内存储的值来判断1.超界 2.前面是墙 3.前面是箱子或者空箱子 再前面是箱子或者墙或者空箱子在用户进行的操作是否执行来实现角色正常的移动，从而实现推箱子。定义IsSuccess()方法来遍历地图数组判断地图上是否存在空箱子来判断游戏是否成功，定义GetNextMap()方法来实现选关，最后定义Success()方法来判断用户是否通过所有关卡，从而判断是否全部闯关成功。 三、部分源码分析 1、素材接口 package 推箱子2;import javax.swing.ImageIcon;public interface MapConfig { //素材图片定义、整合接口/**素材宽度*/ int SOUREC_WIDTH = 50;
