public class LoginAndRegister extends JFrame implements ActionListener {
    // 登入和注册页面的组件
    private JLabel titleLabel;
    private JLabel usernameLabel;
    private JLabel passwordLabel;
    private JTextField usernameText;
    private JPasswordField passwordText;

    private JButton registerConfirmButton;
    private JButton registerCancelButton;

    public LoginAndRegister() {
        // 设置登入页面的标题和大小
        setTitle("Login");
        setSize(500, 300);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        // 创建登入页面的组件
        titleLabel = new JLabel("Login", JLabel.CENTER);
        usernameLabel = new JLabel("Username:");
        passwordLabel = new JLabel("Password:");
        usernameText = new JTextField(20);
        passwordText = new JPasswordField(20);
        loginButton = new JButton("Login");
        registerButton = new JButton("Register");

        // 设置组件的位置和大小
        titleLabel.setBounds(0, 20, 500, 50);

        registerButton.setBounds(250, 200, 100, 30);
        registerButton.addActionListener(this);

        // 将组件添加到登入页面中
        add(titleLabel);
        add(usernameLabel);
        add(usernameText);
        add(passwordLabel);
        add(passwordText);
        add(loginButton);
        add(registerButton);

        // 显示登入页面
        setVisible(true);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == loginButton) {
            // 登入按钮被点击
            String username = usernameText.getText();
            String password = new String(passwordText.getPassword());
            // TODO: 根据用户名和密码进行登入操作
        } else if (e.getSource() == registerButton) {

            String username = registerUsernameText.getText();
            String password = new String(registerPasswordText.getPassword());
            String confirmPassword = new String(registerConfirmPasswordText.getPassword());
            // TODO: 根据用户名和密码进行注册操作
            // 注册成功后关闭注册页面
            registerFrame.dispose();
        } else if (e.getSource() == registerCancelButton) {
            // 注册取消按钮被点击
            registerFrame.dispose();
        }
    }

    private void showRegisterFrame() {
        // 创建注册页面的组件
        registerFrame = new JFrame("Register");
        registerFrame.setSize(500, 300);
        registerFrame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

        registerTitleLabel = new JLabel("Register", JLabel.CENTER);
        registerUsernameLabel = new JLabel("Username:");
        registerPasswordLabel = new JLabel("Password:");
        registerConfirmPasswordLabel = new JLabel("Confirm Password:");
        registerUsernameText = new JTextField(20);
        registerPasswordText = new JPasswordField(20);
        registerConfirmPasswordText = new JPasswordField(20);
        registerConfirmButton = new JButton("Confirm");
        registerConfirmButton.addActionListener(this);
        registerCancelButton = new JButton("Cancel");
        registerCancelButton.addActionListener(this);

        registerTitleLabel.setBounds(0, 20, 500, 50);
        registerTitleLabel.setFont(new Font("Arial", Font.BOLD, 36));
        registerUsernameLabel.setBounds(50, 100, 100, 30);
        registerUsernameText.setBounds(150, 100, 200, 30);
        registerPasswordLabel.setBounds(50, 150, 100, 30);
        registerPasswordText.setBounds(150, 150, 200, 30);

        registerConfirmButton.setBounds(100, 250, 100, 30);
        registerCancelButton.setBounds(250, 250, 100, 30);

        registerFrame.add(registerTitleLabel);
        registerFrame.add(registerUsernameLabel);
        registerFrame.add(registerUsernameText);
        registerFrame.add(registerPasswordLabel);
        registerFrame.add(registerPasswordText);
        registerFrame.add(registerConfirmPasswordLabel);
        registerFrame.add(registerConfirmPasswordText);
        registerFrame.add(registerConfirmButton);
        registerFrame.add(registerCancelButton);

        registerFrame.setVisible(true);
    }

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

这是一个简单的登入和注册页面的示例，你可以根据自己的需求进行修改和美化。
