基于java2048小游戏简单程序设计

上学期学习了一些java设计方法和模式，做个2048练练手再熟悉一下。

项目主要分为element、game、manager三个包。

element：与游戏有关的元素类，包括基本矩形RectObject和用来表示坐标的Point类。

game：与游戏运行主体有关的，包括三个界面的Jpanel，JFrame，以及整个游戏线程控制GameRunThread和游戏主类。

manager：元素管理类，管理所有element，单例模式。

if(MyJFrame.change==true){
			ElementManager.getElementManager().getARandomRect();
			//saveTheStep();
		}
