Java带界面设计的学生信息管理系统代码

以下是一个简单的Java带界面设计的学生信息管理系统的示例代码：

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;

        // 设置窗口标题和大小
        setTitle("学生信息管理系统");
        setSize(800, 600);
        setResizable(false);
        setLocationRelativeTo(null);

        // 创建登录界面
        loginPanel = new JPanel(new GridLayout(3, 2, 5, 5));

        deleteButton = new JButton("删除学生信息");
        deleteButton.addActionListener(this);

        mainPanel.setVisible(false);

        // 创建添加学生信息界面
        addPanel = new JPanel(new GridLayout(6, 2, 5, 5));
        addPanel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
        addPanel.add(new JLabel("姓名：", JLabel.RIGHT));
        addPanel.add(new JTextField());

        queryPanel.add(new JTextField(), BorderLayout.CENTER);
        queryPanel.add(new JButton("查询"), BorderLayout.EAST);
        resultTable = new JTable(10, 5);

        // 创建删除学生信息界面
        deletePanel = new JPanel(new BorderLayout());
        deletePanel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
        deletePanel.add(new JLabel("请输入学号：", JLabel.LEFT), BorderLayout.NORTH);
        deletePanel.add(new JTextField(), BorderLayout.CENTER);
        deletePanel.add(new JButton("删除"), BorderLayout.EAST);
        deletePanel.setVisible(false);

        // 创建标题
        titleLabel = new JLabel("欢迎使用学生信息管理系统", JLabel.CENTER);
        titleLabel.setFont(new Font("微软雅黑", Font.BOLD, 24));

        // 将各个界面添加到窗口中
        getContentPane().add(titleLabel, BorderLayout.NORTH);
        getContentPane().add(loginPanel, BorderLayout.CENTER);
        getContentPane().add(mainPanel, BorderLayout.SOUTH);
        getContentPane().add(addPanel, BorderLayout.CENTER);
        getContentPane().add(queryPanel, BorderLayout.CENTER);
        getContentPane().add(modifyPanel, BorderLayout.CENTER);
        getContentPane().add(deletePanel, BorderLayout.CENTER);

        // 设置窗口可见
        setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == loginButton) { // 登录
            String username = usernameField.getText();
            String password = new String(passwordField.getPassword());
            if (username.equals("admin") && password.equals("123456")) {
                loginPanel.setVisible(false);
                mainPanel.setVisible(true);
            } else {
                JOptionPane.showMessageDialog(this, "用户名或密码错误！", "错误", JOptionPane.ERROR_MESSAGE);
            }
        } else if (e.getSource() == addButton) { // 添加学生信息
            mainPanel.setVisible(false);
            addPanel.setVisible(true);
        } else if (e.getSource() == queryButton) { // 查询学生信息
            mainPanel.setVisible(false);
            queryPanel.setVisible(true);
        } else if (e.getSource() == modifyButton) { // 修改学生信息
            mainPanel.setVisible(false);

        } else if (e.getSource() == deleteButton) { // 删除学生信息
            mainPanel.setVisible(false);
            deletePanel.setVisible(true);
        }
    }

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

请注意，上述代码只是一个简单的示例，实际上还需要完成各个功能模块的业务逻辑。同时，为了更好地组织代码，建议将各个功能模块的代码分别封装在不同的类中，并使用MVC模式进行设计。
