实现界面登陆，退出功能的java代码怎么写？
CS结构系统登陆界面，java代码的退出如下：public void init() {
this.setTitle("用户登录界面");
this.add(createCenterPane());
this.setDefaultCloseOperation(this.DO_NOTHING_ON_CLOSE);
this.setSize(new Dimension(450, 335));
this.setLocationRelativeTo(null);
// this.setVisible(true);
this.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
int choose = JOptionPane.showConfirmDialog(null, "是否要退出登录界面登陆界面，java代码？",
"系统提示：", JOptionPane.YES_NO_OPTION);
if (choose == JOptionPane.YES_OPTION) {
System.exit(1);
}
}
});
}其中this为JFrame对象。BS结构的退出直接用windows.close()方法就行了！

Q1: 用java做好的登陆界面，当登陆成功后跳转到下个页面的代码是什么？
用java做好的登陆界面，当登陆成功后跳转到下个页面的代码如下：
如果登陆验证是在jsp中，那么跳转可以写成
1.response.sendRedirct("跳转到页面");
2.jsp:forward page="跳转页面"/
3.response.setHeader("Location","");
如果是登陆验证是在servlet中，那么中转可以写成
1.response.sendRedirect("/a.jsp");
2.RequestDispatcher dispatcher = request.getRequestDispatcher("/a.jsp");
dispatcher .forward(request, response);
也可以使用js代码实现：
script
function validate(){
window.location.href="/index.jsp";
}
/script
Q2: 登录界面的java代码，分别有教师登录，管理员登录，学生登录，右边是用户名和密码，见图。
分三个包，自己建个包，导进去就ok了，数据库是access的。

编程的注意事项:
1、Java是一门面向对象编程语言，不仅吸收了C++语言的各种优点，还摒弃了C++里难以理解的多继承、指针等概念，因此Java语言具有功能强大和简单易用两个特征。Java语言作为静态面向对象编程语言的代表，极好地实现了面向对象理论，允许程序员以优雅的思维方式进行复杂的编程。
2、 Java具有简单性、面向对象、分布式、健壮性、安全性、平台独立与可移植性、多线程、动态性等特点。Java可以编写桌面应用程序、Web应用程序、分布式系统和嵌入式系统应用程序等。
3、2006年11月13日，Java技术的发明者Sun公司宣布，将Java技术作为免费软件对外发布。Sun公司正式发布的有关Java平台标准版的第一批源代码，以及Java迷你版的可执行源代码。从2007年3月起，全世界所有的开发人员均可对Java源代码进行修改。
