java.awt 包含用于创建用户界面和绘制图形图像的所有类。
java.awt.event 提供处理由 AWT 组件所激发的各类事件的接口和类。
.awt 抽象窗口工具包 Abstract Window Toolkit
awt Java提供的用来建立和设置Java的图形用户界面的基本工具
JMenu 菜单的该实现是一个包含 JMenuItem 的弹出窗口
用户选择 JMenuBar 上的项时会显示该 JMenuItem。
AbstractAction是java开发语言中swing软件包中的一个类。
AbstracAction 此类提供 JFC Action 接口的默认实现。
JFC Java Foundation Classes
是一个图形框架（Graphical Framework）
依据此框架可建构出具有移携性（Portable）的Java式GUI图形式使用者界面。
AbstractAction(String name, Icon icon)
用指定描述字符串和指定图标定义一个 Action 对象。
