并且游戏有一定的难度和娱乐性。
开发一个Mario类。
一个场景类，以及敌人类，障碍物类。
让超级玛丽能够在场景中完成各种动作。
并且有场景的切换等等功能。
游戏中设计了一些很有意思的陷阱，玩家一步小心掉入陷阱，超级玛丽就会死亡。
这样会给人意想不到的惊奇，达到娱乐大众，增加游戏难度的效果。
游戏的设计匠心独具，并且都经过了各种测试，除了为玩家增加一些意想不到的游戏陷阱以外，还必须保证玩家能够通关。
1.2程序功能图如图1所示：图11.3程序类图系统的整体类图的框架如图2所示。
首先是窗体类。
他需要调用到Mario和BackGround类中的方法。
以便动态的显示Mario类和BackGround。
而BackGround里面又包含了Enemy和Obstruction。
Enemy，Obstruction和Mario类又调用静态类StaticValue的方法，用以显示真实的图片。
而StaticValue则是一个静态类，将存储在硬盘的图片资源加载进入内存以便其他模块调用。
图22详细设计2.1MyFrame实现2.1.1窗体对象的序列图窗体对象继承了JFrame类并且实现了Runnable接口。
作为窗体对象，它首先显示窗体，绘制背景。
然后启动线程。
在run方法里面动态得绘制窗体中需要显示的Mario 的图片，障碍物的图片，敌人的图片。
该窗体的run方法是一个死循环，每次执行一个循环调用sleep方法睡眠50毫秒。
序列图如图3所示。
图32.1.2 Myframe详细类图private Mario mario;//Mario对象private boolean isStart = false;//标识游戏是否已经开始this.paintAllEnemys(g2);//绘制所有的敌人this.paintAllObstruction(g2);//绘制所有障碍物2.2 Mario实现2.2.1 Mario对象的序列图因为需要有一个专门的线程来实时监测Mario的移动状况，和障碍物和敌人的碰撞情况。
所以让Mario类继承了Runnable接口。
Mario先启动线程。
该线程的run方法也是一个死循环。
首先根据Mario的状态changeMarioImage方法修改Mario的显示图片。
再根据Mario的determinexy方法决定Mario的移动。
然后通过deterMarioWithObstruction方法检测Mario和障碍物之间的碰撞，在根据marioTouchEnemys方法检测Mario和敌人之间的碰撞。
然后调用sleep()方法让线程休息5毫秒。
如此结束一个循环。
序列图如图4所示。
