        //3.定义sql
        String sql = "INSERT INTO stu VALUES(10,'路飞',28,'男','陕西',58,48,'1996-4-3')";

        //4.获取执行sql的对象 Statement
        Statement stmt = conn.createStatement();

        //5.执行sql
        int count = stmt.executeUpdate(sql);

        //6.处理结果
        System.out.println(count);

        //7.释放资源
        stmt.close();
        conn.close();
