1.功能：
键盘上下左右键控制飞机走向以躲避随机飞过来的子弹，存活时间越长得分越高
2.主要界面：
3.页面加载框架类：

* 加载窗口
*/

setSize(Constant.Frame_wide, Constant.Frame_high);// 画布大小，windows类下面方法，继承得到的
setLocation(0, 0);// 画布左上角位置
setVisible(true);// 画布可见
// addWindowListener方法作用是调出来的窗口能×掉
// 调用addWindowListener方法，WindowAdapter属于方法addWindowListener的内部类
// new WindowAdapter()为创建对象，这个对象要重写方法

}
// window是Frame的父类，paint是Frame的一个方法
