请按照如下要求编写JDBC程序，用于对数据库中的tb_users表的数据进行操作（请上传代码和运行截图）。 1. 创建数据库user，并创建 tb_users表，该表包含id(int) ,name varchar(20),sex carchar(10) email varchar(30),birthday date 5个字段。 2.创建Admin类，首先编写数据库连接方法getConn()。 3.编写插入方法insert()。 4.编写修改方法update()。 5.编写查询方法select()。 6.编写delete（）方法。 7.创建Test类，测试程序，结果输出在控制台上。

很抱歉，作为AI语言模型，我没有权限上传代码和运行截图。但我可以提供JDBC程序的代码示例：

Admin.java

import java.sql.*;

public class Admin {
    private static final String JDBC_DRIVER = "com.mysql.jdbc.Driver";
    private static final String DB_URL = "jdbc:mysql://localhost:3306/user";
    private static final String USER = "root";
    private static final String PASS = "password";

    private Connection conn = null;
    private PreparedStatement pstmt = null;

    public Connection getConn() {
        try {
            Class.forName(JDBC_DRIVER);
            conn = DriverManager.getConnection(DB_URL, USER, PASS);
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return conn;
    }

    public void insert(int id, String name, String sex, String email, String birthday) {
        conn = getConn();
        try {
            pstmt = conn.prepareStatement("insert into tb_users(id,name,sex,email,birthday) values(?,?,?,?,?)");
            pstmt.setInt(1, id);
            pstmt.setString(2, name);
            pstmt.setString(3, sex);
            pstmt.setString(4, email);
            pstmt.setString(5, birthday);
            pstmt.executeUpdate();
            pstmt.close();
            conn.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }

    public void update(int id, String name, String sex, String email, String birthday) {
        conn = getConn();
        try {
            pstmt = conn.prepareStatement("update tb_users set name=?,sex=?,email=?,birthday=? where id=?");
            pstmt.setString(1, name);
            pstmt.setString(2, sex);
            pstmt.setString(3, email);
            pstmt.setString(4, birthday);
            pstmt.setInt(5, id);
            pstmt.executeUpdate();
            pstmt.close();
            conn.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }

    public void select() {
        conn = getConn();
        try {
            pstmt = conn.prepareStatement("select * from tb_users");
            ResultSet rs = pstmt.executeQuery();
            while (rs.next()) {
                int id = rs.getInt("id");
                String name = rs.getString("name");
                String sex = rs.getString("sex");
                String email = rs.getString("email");
                String birthday = rs.getString("birthday");
                System.out.println(id + "\t" + name + "\t" + sex + "\t" + email + "\t" + birthday);
            }
            rs.close();
            pstmt.close();
            conn.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }

    public void delete(int id) {
        conn = getConn();
        try {
            pstmt = conn.prepareStatement("delete from tb_users where id=?");
            pstmt.setInt(1, id);
            pstmt.executeUpdate();
            pstmt.close();
            conn.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}

Test.java

public class Test {
    public static void main(String[] args) {
        Admin admin = new Admin();

        // 插入数据
        admin.insert(1, "张三", "男", "zhangsan@qq.com", "1990-01-01");
        admin.insert(2, "李四", "女", "lisi@qq.com", "1995-02-02");

        // 查询数据
        System.out.println("查询数据：");
        admin.select();

        // 修改数据
        System.out.println("修改数据：");
        admin.update(1, "张三", "男", "zhangsan@sina.com", "1990-01-01");
        admin.select();

        // 删除数据
        System.out.println("删除数据：");
        admin.delete(2);
        admin.select();
    }
}
