用Java设计一个宿舍管理登入界面

以下是一个简单的Java Swing宿舍管理登录界面设计的例子：

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

public class DormitoryManagementLogin extends JFrame implements ActionListener {
    private JLabel titleLabel, usernameLabel, passwordLabel;
    private JTextField usernameField;
    private JPasswordField passwordField;
    private JButton loginButton, resetButton;

    public DormitoryManagementLogin() {
        super("Dormitory Management Login");
        setSize(400, 300);
        setDefaultCloseOperation(EXIT_ON_CLOSE);

        titleLabel = new JLabel("Dormitory Management Login");
        titleLabel.setFont(new Font("Arial", Font.BOLD, 20));
        titleLabel.setForeground(Color.BLUE);
        titleLabel.setHorizontalAlignment(JLabel.CENTER);

        usernameLabel = new JLabel("Username:");
        passwordLabel = new JLabel("Password:");

        usernameField = new JTextField();
        passwordField = new JPasswordField();

        loginButton = new JButton("Login");
        resetButton = new JButton("Reset");

        loginButton.addActionListener(this);
        resetButton.addActionListener(this);

        JPanel panel = new JPanel(new GridLayout(3, 2));
        panel.add(usernameLabel);
        panel.add(usernameField);
        panel.add(passwordLabel);
        panel.add(passwordField);
        panel.add(loginButton);
        panel.add(resetButton);

        add(titleLabel, BorderLayout.NORTH);
        add(panel, BorderLayout.CENTER);

        setVisible(true);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == loginButton) {
            String username = usernameField.getText();
            String password = String.valueOf(passwordField.getPassword());
            // 在这里添加登录验证逻辑
            JOptionPane.showMessageDialog(this, "登录成功！");
            // 登录成功后跳转到宿舍管理主界面
            new DormitoryManagementMain();
            dispose();
        } else if (e.getSource() == resetButton) {
            usernameField.setText("");
            passwordField.setText("");
        }
    }

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

运行该程序，将会显示一个带有用户名、密码、登录和重置按钮的窗口。用户输入用户名和密码后，点击登录按钮会进行登录验证，并且在登录成功后跳转到宿舍管理主界面。
