java声明StudentJFrame类写一个Student对象信息管理

好的，我可以帮你写一个简单的Java程序来管理Student对象的信息。首先，我们需要声明一个名为StudentJFrame的类来设计界面，然后在其中添加相应的组件来实现增加、删除、查找和修改学生信息的功能。接下来，我们可以在主函数中创建一个Student对象数组，用来存储学生对象的信息。

以下是一个简单的实现示例代码：

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

public class StudentJFrame extends JFrame implements ActionListener {
    private JLabel label1, label2, label3, label4;
    private JTextField text1, text2, text3, text4;
    private JButton btnAdd, btnDelete, btnSearch, btnUpdate;
    private JPanel panel1, panel2;

    private Student[] students = new Student[100];
    private int num = 0;

    public StudentJFrame() {
        super("Student Information Management");

        label1 = new JLabel("学号");
        label2 = new JLabel("姓名");
        label3 = new JLabel("性别");
        label4 = new JLabel("年龄");

        text1 = new JTextField(10);
        text2 = new JTextField(10);
        text3 = new JTextField(10);
        text4 = new JTextField(10);

        btnAdd = new JButton("添加");
        btnDelete = new JButton("删除");
        btnSearch = new JButton("查找");
        btnUpdate = new JButton("修改");

        panel1 = new JPanel();
        panel1.setLayout(new GridLayout(4, 2));
        panel1.add(label1);
        panel1.add(text1);
        panel1.add(label2);
        panel1.add(text2);
        panel1.add(label3);
        panel1.add(text3);
        panel1.add(label4);
        panel1.add(text4);

        panel2 = new JPanel();
        panel2.setLayout(new GridLayout(1, 4));
        panel2.add(btnAdd);
        panel2.add(btnDelete);
        panel2.add(btnSearch);
        panel2.add(btnUpdate);

        add(panel1, BorderLayout.CENTER);
        add(panel2, BorderLayout.SOUTH);

        btnAdd.addActionListener(this);
        btnDelete.addActionListener(this);
        btnSearch.addActionListener(this);
        btnUpdate.addActionListener(this);

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(400, 200);
        setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == btnAdd) {
            // 添加学生信息
            students[num] = new Student(text1.getText(), text2.getText(), text3.getText(), Integer.parseInt(text4.getText()));
            num++;
            JOptionPane.showMessageDialog(this, "添加成功！");
        } else if (e.getSource() == btnDelete) {
            // 删除学生信息
            String id = JOptionPane.showInputDialog(this, "请输入要删除的学生学号：");
            boolean flag = false;
            for (int i = 0; i < num; i++) {
                if (students[i].getId().equals(id)) {
                    for (int j = i; j < num - 1; j++) {
                        students[j] = students[j + 1];
                    }
                    num--;
                    flag = true;
                    JOptionPane.showMessageDialog(this, "删除成功！");
                    break;
                }
            }
            if (!flag) {
                JOptionPane.showMessageDialog(this, "未找到该学生记录！");
            }
        } else if (e.getSource() == btnSearch) {
            // 查找学生信息
            String id = JOptionPane.showInputDialog(this, "请输入要查找的学生学号：");
            boolean flag = false;
            for (int i = 0; i < num; i++) {
                if (students[i].getId().equals(id)) {
                    text1.setText(students[i].getId());
                    text2.setText(students[i].getName());
                    text3.setText(students[i].getGender());
                    text4.setText(String.valueOf(students[i].getAge()));
                    flag = true;
                    JOptionPane.showMessageDialog(this, "查找成功！");
                    break;
                }
            }
            if (!flag) {
                JOptionPane.showMessageDialog(this, "未找到该学生记录！");
            }
        } else if (e.getSource() == btnUpdate) {
            // 修改学生信息
            String id = JOptionPane.showInputDialog(this, "请输入要修改的学生学号：");
            boolean flag = false;
            for (int i = 0; i < num; i++) {
                if (students[i].getId().equals(id)) {
                    students[i].setName(text2.getText());
                    students[i].setGender(text3.getText());
                    students[i].setAge(Integer.parseInt(text4.getText()));
                    flag = true;
                    JOptionPane.showMessageDialog(this, "修改成功！");
                    break;
                }
            }
            if (!flag) {
                JOptionPane.showMessageDialog(this, "未找到该学生记录！");
            }
        }
    }

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

class Student {
    private String id;
    private String name;
    private String gender;
    private int age;

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

    public String getId() {
        return id;
    }

    public String getName() {
        return name;
    }

    public String getGender() {
        return gender;
    }

    public int getAge() {
        return age;
    }

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

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

    public void setAge(int age) {
        this.age = age;
    }
}

以上代码实现了一个简单的学生信息管理系统，可以通过界面添加、删除、查找和修改学生信息。注意：这只是一个简单的实现示例，完整的学生信息管理系统需要考虑更多的情况，比如数据存储、数据校验、界面美化等。
