登录页面Java代码编写

以下是一个简单的Java登录页面代码示例：

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class Login extends JFrame implements ActionListener {
    private JLabel userLabel, passwordLabel;
    private JTextField userText;
    private JPasswordField passwordText;
    private JButton loginButton, resetButton;

    public Login() {
        setTitle("登录页面");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(300, 150);
        setLocationRelativeTo(null);

        userLabel = new JLabel("用户名:");
        passwordLabel = new JLabel("密码:");
        userText = new JTextField(10);
        passwordText = new JPasswordField(10);
        loginButton = new JButton("登录");
        resetButton = new JButton("重置");

        JPanel panel = new JPanel(new GridLayout(3, 2));
        panel.add(userLabel);
        panel.add(userText);
        panel.add(passwordLabel);
        panel.add(passwordText);
        panel.add(loginButton);
        panel.add(resetButton);

        add(panel, BorderLayout.CENTER);
        loginButton.addActionListener(this);
        resetButton.addActionListener(this);
        setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == loginButton) {
            String user = userText.getText();
            String password = new String(passwordText.getPassword());
            if (user.equals("admin") && password.equals("123456")) {
                JOptionPane.showMessageDialog(null, "登录成功");
            } else {
                JOptionPane.showMessageDialog(null, "用户名或密码错误");
            }
        } else if (e.getSource() == resetButton) {
            userText.setText("");
            passwordText.setText("");
        }
    }

    public static void main(String[] args) {
        new Login();
    }
}
