图形化插件，编写Register类和MainFrame类，其界面学号 姓名密码 注册 密码(确认)性别 专业 男 y 计算机科学与技术 我已阅读并同意注册规则 注册 重置java代码

以下是使用 Java Swing 实现的 Register 和 MainFrame 类的示例代码，其中包含了你提到的所有控件和布局：

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

public class Register extends JFrame implements ActionListener {
    private JLabel labelNumber, labelName, labelPassword, labelConfirmPassword, labelGender, labelMajor;
    private JTextField tfNumber, tfName;
    private JPasswordField pfPassword, pfConfirmPassword;
    private JRadioButton rbMale, rbFemale;
    private ButtonGroup bgGender;
    private JComboBox<String> cbMajor;
    private JCheckBox cbAgree;
    private JButton btnRegister, btnReset;

    public Register() {
        super("注册");

        // 创建控件
        labelNumber = new JLabel("学号：");
        labelName = new JLabel("姓名：");
        labelPassword = new JLabel("密码：");
        labelConfirmPassword = new JLabel("确认密码：");
        labelGender = new JLabel("性别：");
        labelMajor = new JLabel("专业：");
        tfNumber = new JTextField(10);
        tfName = new JTextField(10);
        pfPassword = new JPasswordField(10);
        pfConfirmPassword = new JPasswordField(10);
        rbMale = new JRadioButton("男", true);
        rbFemale = new JRadioButton("女", false);
        bgGender = new ButtonGroup();
        bgGender.add(rbMale);
        bgGender.add(rbFemale);
        cbMajor = new JComboBox<>(new String[]{"计算机科学与技术", "软件工程", "信息安全"});
        cbAgree = new JCheckBox("我已阅读并同意注册规则");
        btnRegister = new JButton("注册");
        btnReset = new JButton("重置");

        // 布局
        JPanel panel = new JPanel(new GridBagLayout());
        GridBagConstraints c = new GridBagConstraints();
        c.gridx = 0;
        c.gridy = 0;
        c.anchor = GridBagConstraints.EAST;
        panel.add(labelNumber, c);
        c.gridy++;
        panel.add(labelName, c);
        c.gridy++;
        panel.add(labelPassword, c);
        c.gridy++;
        panel.add(labelConfirmPassword, c);
        c.gridy++;
        panel.add(labelGender, c);
        c.gridy++;
        panel.add(labelMajor, c);
        c.gridy++;
        c.gridwidth = 2;
        panel.add(cbAgree, c);
        c.gridy = 0;
        c.gridx++;
        c.anchor = GridBagConstraints.WEST;
        panel.add(tfNumber, c);
        c.gridy++;
        panel.add(tfName, c);
        c.gridy++;
        panel.add(pfPassword, c);
        c.gridy++;
        panel.add(pfConfirmPassword, c);
        c.gridy++;
        JPanel panelGender = new JPanel();
        panelGender.add(rbMale);
        panelGender.add(rbFemale);
        panel.add(panelGender, c);
        c.gridy++;
        panel.add(cbMajor, c);
        c.gridy++;
        c.gridwidth = 1;
        c.anchor = GridBagConstraints.CENTER;
        panel.add(btnRegister, c);
        c.gridx++;
        panel.add(btnReset, c);
        add(panel);

        // 绑定事件
        btnRegister.addActionListener(this);
        btnReset.addActionListener(this);

        // 设置窗口
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(400, 300);
        setLocationRelativeTo(null);
        setResizable(false);
        setVisible(true);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == btnRegister) {
            // 注册逻辑
        } else if (e.getSource() == btnReset) {
            // 重置表单
            tfNumber.setText("");
            tfName.setText("");
            pfPassword.setText("");
            pfConfirmPassword.setText("");
            rbMale.setSelected(true);
            cbMajor.setSelectedIndex(0);
            cbAgree.setSelected(false);
        }
    }
}

public class MainFrame extends JFrame implements ActionListener {
    private JLabel labelWelcome;
    private JButton btnRegister;

    public MainFrame() {
        super("主界面");

        // 创建控件
        labelWelcome = new JLabel("欢迎使用");
        btnRegister = new JButton("注册");

        // 布局
        JPanel panel = new JPanel(new GridBagLayout());
        GridBagConstraints c = new GridBagConstraints();
        c.gridx = 0;
        c.gridy = 0;
        c.insets = new Insets(20, 0, 0, 0);
        panel.add(labelWelcome, c);
        c.gridy++;
        panel.add(btnRegister, c);
        add(panel);

        // 绑定事件
        btnRegister.addActionListener(this);

        // 设置窗口
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(400, 300);
        setLocationRelativeTo(null);
        setResizable(false);
        setVisible(true);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == btnRegister) {
            // 打开注册界面
            Register register = new Register();
            register.setVisible(true);
        }
    }

    public static void main(String[] args) {
        MainFrame mainFrame = new MainFrame();
    }
}

这个示例代码中，Register 类实现了注册界面，其中的 actionPerformed 方法可以处理注册和重置按钮的事件。MainFrame 类实现了主界面，其中的 actionPerformed 方法可以打开注册界面。你可以根据自己的需要修改控件和布局。
