java用gui编写一个学生管理系统

好的，下面是一个简单的学生管理系统的GUI界面：

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

public class StudentManagementSystemGUI extends JFrame implements ActionListener {
    private JLabel titleLabel, nameLabel, ageLabel, genderLabel, majorLabel;
    private JTextField nameTextField, ageTextField, majorTextField;
    private JRadioButton maleRadioButton, femaleRadioButton;
    private ButtonGroup genderButtonGroup;
    private JButton addButton, clearButton;
    private JTextArea displayTextArea;
    private JScrollPane scrollPane;

    public StudentManagementSystemGUI() {
        // 设置窗口标题
        setTitle("学生管理系统");

        // 设置窗口大小
        setSize(400, 400);

        // 设置窗口位置
        setLocationRelativeTo(null);

        // 设置窗口关闭方式
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        // 添加标题标签
        titleLabel = new JLabel("学生管理系统");
        titleLabel.setFont(new Font("宋体", Font.BOLD, 20));
        titleLabel.setHorizontalAlignment(SwingConstants.CENTER);
        add(titleLabel, BorderLayout.NORTH);

        // 添加表单面板
        JPanel formPanel = new JPanel(new GridLayout(5, 2, 10, 10));
        nameLabel = new JLabel("姓名：");
        nameTextField = new JTextField();
        ageLabel = new JLabel("年龄：");
        ageTextField = new JTextField();
        genderLabel = new JLabel("性别：");
        maleRadioButton = new JRadioButton("男");
        femaleRadioButton = new JRadioButton("女");
        genderButtonGroup = new ButtonGroup();
        genderButtonGroup.add(maleRadioButton);
        genderButtonGroup.add(femaleRadioButton);
        majorLabel = new JLabel("专业：");
        majorTextField = new JTextField();
        formPanel.add(nameLabel);
        formPanel.add(nameTextField);
        formPanel.add(ageLabel);
        formPanel.add(ageTextField);
        formPanel.add(genderLabel);
        formPanel.add(maleRadioButton);
        formPanel.add(new JLabel());
        formPanel.add(femaleRadioButton);
        formPanel.add(majorLabel);
        formPanel.add(majorTextField);
        add(formPanel, BorderLayout.CENTER);

        // 添加按钮面板
        JPanel buttonPanel = new JPanel(new FlowLayout());
        addButton = new JButton("添加");
        clearButton = new JButton("清空");
        addButton.addActionListener(this);
        clearButton.addActionListener(this);
        buttonPanel.add(addButton);
        buttonPanel.add(clearButton);
        add(buttonPanel, BorderLayout.SOUTH);

        // 添加显示文本区域
        displayTextArea = new JTextArea();
        scrollPane = new JScrollPane(displayTextArea);
        add(scrollPane, BorderLayout.EAST);

        // 显示窗口
        setVisible(true);
    }

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

    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == addButton) {
            String name = nameTextField.getText();
            int age = Integer.parseInt(ageTextField.getText());
            String gender = maleRadioButton.isSelected() ? "男" : "女";
            String major = majorTextField.getText();
            String studentInfo = "姓名：" + name + " 年龄：" + age + " 性别：" + gender + " 专业：" + major + "\n";
            displayTextArea.append(studentInfo);
        } else if (e.getSource() == clearButton) {
            nameTextField.setText("");
            ageTextField.setText("");
            genderButtonGroup.clearSelection();
            majorTextField.setText("");
            displayTextArea.setText("");
        }
    }
}

这个学生管理系统GUI界面包含一个标题标签、一个表单面板、一个按钮面板和一个显示文本区域。用户可以在表单面板中输入学生的姓名、年龄、性别和专业信息，点击“添加”按钮可以将该学生的信息添加到显示文本区域中，点击“清空”按钮可以清空表单面板和显示文本区域中的内容。
