当单击退出系统，该系统就会直接退出，相应的代码如下： private class ExitSystemAction implements ActionListener
{
}
}
public void actionPerformed(ActionEvent arg0) { System.exit(0);
5.2.2人员管理功能
（1）人员信息录入
单击人员信息录入，系统会跳出人员信息录入窗口，程序运行结果如图5.4所示：
图5.4 人员信息录入窗体运行结果
当用户单击录入按钮，则信息则会添加到数据库的nformation表中，当单击取消按钮，则文本框中的内容全部为空，可以重新输入。相应的代码如下：
人员信息录入代码： package com.zky.www.view;
public class Addpeople extends JInternalFrame {
