用java写一个学生对象信息管理的面板

好的，我可以为您提供一个简单的Java学生信息管理面板的代码，您可以根据需要进行修改和完善。以下是示例代码：

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.ArrayList;

public class StudentPanel extends JFrame implements ActionListener {
    private JLabel nameLabel, idLabel, genderLabel, majorLabel;
    private JTextField nameField, idField, majorField;
    private JRadioButton maleRadioButton, femaleRadioButton;
    private ButtonGroup genderGroup;
    private JButton addButton, deleteButton, updateButton, clearButton;
    private JList<Student> studentList;
    private DefaultListModel<Student> listModel;
    private ArrayList<Student> studentArrayList;

    public StudentPanel() {
        setTitle("学生信息管理系统");
        setSize(500, 500);
        setLocationRelativeTo(null);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        nameLabel = new JLabel("姓名");
        idLabel = new JLabel("学号");
        genderLabel = new JLabel("性别");
        majorLabel = new JLabel("专业");
        nameField = new JTextField(10);
        idField = new JTextField(10);
        majorField = new JTextField(10);
        maleRadioButton = new JRadioButton("男");
        femaleRadioButton = new JRadioButton("女");
        genderGroup = new ButtonGroup();
        genderGroup.add(maleRadioButton);
        genderGroup.add(femaleRadioButton);
        addButton = new JButton("添加");
        deleteButton = new JButton("删除");
        updateButton = new JButton("更新");
        clearButton = new JButton("清空");
        studentArrayList = new ArrayList<>();
        listModel = new DefaultListModel<>();
        studentList = new JList<>(listModel);
        studentList.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

        JPanel inputPanel = new JPanel(new GridLayout(4, 2));
        inputPanel.add(nameLabel);
        inputPanel.add(nameField);
        inputPanel.add(idLabel);
        inputPanel.add(idField);
        inputPanel.add(genderLabel);
        inputPanel.add(maleRadioButton);
        inputPanel.add(new JLabel(""));
        inputPanel.add(femaleRadioButton);
        inputPanel.add(majorLabel);
        inputPanel.add(majorField);

        JPanel buttonPanel = new JPanel(new GridLayout(1, 4));
        buttonPanel.add(addButton);
        buttonPanel.add(deleteButton);
        buttonPanel.add(updateButton);
        buttonPanel.add(clearButton);

        JPanel listPanel = new JPanel();
        listPanel.add(new JScrollPane(studentList));

        Container container = getContentPane();
        container.setLayout(new BorderLayout());
        container.add(inputPanel, BorderLayout.NORTH);
        container.add(buttonPanel, BorderLayout.CENTER);
        container.add(listPanel, BorderLayout.SOUTH);

        addButton.addActionListener(this);
        deleteButton.addActionListener(this);
        updateButton.addActionListener(this);
        clearButton.addActionListener(this);
        studentList.addListSelectionListener(e -> {
            if (studentList.getSelectedIndex() != -1) {
                Student student = studentList.getSelectedValue();
                nameField.setText(student.getName());
                idField.setText(student.getId());
                majorField.setText(student.getMajor());
                if (student.getGender().equals("男")) {
                    maleRadioButton.setSelected(true);
                } else {
                    femaleRadioButton.setSelected(true);
                }
            }
        });
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == addButton) {
            String name = nameField.getText().trim();
            String id = idField.getText().trim();
            String gender = maleRadioButton.isSelected() ? "男" : "女";
            String major = majorField.getText().trim();
            Student student = new Student(name, id, gender, major);
            studentArrayList.add(student);
            listModel.addElement(student);
        } else if (e.getSource() == deleteButton) {
            int index = studentList.getSelectedIndex();
            if (index != -1) {
                Student student = listModel.getElementAt(index);
                studentArrayList.remove(student);
                listModel.remove(index);
            }
        } else if (e.getSource() == updateButton) {
            int index = studentList.getSelectedIndex();
            if (index != -1) {
                Student student = listModel.getElementAt(index);
                student.setName(nameField.getText().trim());
                student.setId(idField.getText().trim());
                student.setGender(maleRadioButton.isSelected() ? "男" : "女");
                student.setMajor(majorField.getText().trim());
                listModel.setElementAt(student, index);
            }
        } else if (e.getSource() == clearButton) {
            nameField.setText("");
            idField.setText("");
            maleRadioButton.setSelected(true);
            majorField.setText("");
            studentList.clearSelection();
        }
    }

    private static class Student {
        private String name;
        private String id;
        private String gender;
        private String major;

        public Student(String name, String id, String gender, String major) {
            this.name = name;
            this.id = id;
            this.gender = gender;
            this.major = major;
        }

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public String getId() {
            return id;
        }

        public void setId(String id) {
            this.id = id;
        }

        public String getGender() {
            return gender;
        }

        public void setGender(String gender) {
            this.gender = gender;
        }

        public String getMajor() {
            return major;
        }

        public void setMajor(String major) {
            this.major = major;
        }

        @Override
        public String toString() {
            return name + " " + id;
        }
    }

    public static void main(String[] args) {
        new StudentPanel().setVisible(true);
    }
}

该示例代码实现了一个简单的学生信息管理系统，包括添加、删除、更新和清空功能。该系统使用了Java Swing界面库来创建用户界面。

在该示例代码中，我们首先创建了一个学生类`Student`，包含姓名、学号、性别和专业四个属性，并且提供了相应的getter和setter方法。

然后，我们创建了一个JFrame窗口，分别添加了输入框、单选按钮、按钮和列表框等组件来实现用户界面。在添加、删除、更新和清空功能的实现中，我们使用了ArrayList和DefaultListModel两个类来存储和管理学生对象。

希望这个示例代码对您有帮助！
