构思
首先，要把整体的游戏框架和内容构思出来(根据预先构思游戏里存在的组件内容和游戏功能抽象出指定类)。以我的小游戏为例：
-
1.主界面框架类：
显示开始界面 -
2.弹出界面类：
JDialog 窗体的功能是从一个窗体中弹出另一个窗体，就像是在使用 IE 浏览器时弹出的确定对话框，JDialog 窗体与 JFrame 窗体形式基本相同，设置窗体的特性时调用的方法名称都基本相同，如设置窗体大小、窗体关闭状态等 -
3.游戏面板类：GamePanel (extends JPanel)
真正显示飞机大战动态游戏画面，并且还添加了按钮JButton用于控制游戏开始暂停。 -
4.玩家飞机类：Hero
移动玩家飞机、画玩家飞机等其他与玩家飞机相关的方法 -
5.敌机类：AirPlane
移动敌机、画敌机 -
6.子弹类
移动子弹、绘制子弹 -
7碰撞类：Collision
检测各种碰撞情况 -
8.主类：Main
开启程序
