IT技术home

用Java设计一个登录页面，不用连接数据库 ， 只要把用户和密码信息存放在文本里面 ， 怎样设计代码？？？/* Main.java
*
* Created on __DATE__, __TIME__
*/
import javax.swing.JOptionPane;
/**
*
* @author__USER__
*/
public class Main extends javax.swing.JFrame {
/** Creates new form Main */
public Main() {
initComponents();
}
/** This method is called from within the constructor to
* initialize the form.
* WARNING: Do NOT modify this code. The content of this method is
* always regenerated by the Form Editor.

jPanel1 = new javax.swing.JPanel();//标签
jLabel1 = new javax.swing.JLabel();
jLabel2 = new javax.swing.JLabel();

jButton2 = new javax.swing.JButton();//
jTextField1 = new javax.swing.JTextField();//文本框
jTextField2 = new javax.swing.JTextField();
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);//关闭时java设计登录界面代码的操作，即退出程序
setTitle("登录界面");//设置标题：欢迎使用股票管理系统
setResizable(false);//设置窗口不可调节大小
jLabel1.setFont(new java.awt.Font("微软雅黑", 0, 18));//设置标签的字体
jLabel1
.setText("您好，请输入信息");
jLabel2.setText("用户名");
jLabel3.setText("用户密码");
jButton1.setText("登录");
jButton1.addActionListener(new java.awt.event.ActionListener() {//采用匿名内部类来实现按钮监听功能
public void actionPerformed(java.awt.event.ActionEvent evt) {
jButton1ActionPerformed(evt);
}
});
jButton2.setText("退出");
jButton2.addActionListener(new java.awt.event.ActionListener() {//同上
