使用KeyListener接口
使用MouseListener接口，其中MouseEvent中有getButton（），getX（），getY（）等方法
setSelected（）；是否被选中
setText（String）；设置显示文本
setIcon（Icon）；设置图片
其事件处理使用ItenListener
JCheckBox（）；创建文本对象
其事件处理也是用ItemListener接口
int[] getSeletrdIndices（）；返回所选择的所有数组
Jlist（ListModel/Object[] listData/Vector<?>listData）；构造JList
其事件处理使用ListSelectionListener接口
JMenu、JMenuBar、JMenuItem可实现简单的菜单外观，使用事件监听可对应作出一些功能的实现，如代码记事本
