Java期末课程设计——ATM柜员机模拟系统

---

目录

一、设计要求

二、截图

三、设计思路

四、项目结构截图

五、使用说明

六、部分代码

七、资源链接

---

一、设计要求

       使用图形用户界面。当输入给定的卡号和密码（初始卡号和密码为123456）时，系统能登录ATM柜员机系统，用户可以按照以下规则进行：

       1）查询余额：初始余额为10000元

       2）ATM取款：每次取款金额为100的倍数，总额不超过5000元，支取金额不允许透支。

       3）ATM存款：不能出现负存款。

       4）修改密码：新密码长度不小于6位，不允许出现6位完全相同的情况，只有旧密码正确，新密码符合要求，且两次输入相同的情况下才可以成功修改密码。

      5）使用数据库保存数据

二、截图

                    

                  

               

             

三、设计思路

       整体项目分为页面、vo用户类、dao层、action类

      1）页面分为：登录页、菜单主页、余额查询、转账、密码修改、存款、自定义存款、取款。页面使用NetBeans拖拽成。

      2）vo用户类包含用户名、密码、账户余额

      3）dao采用JDBC链接数据库，设计对用户信息的操作，包括：通过账号查找用户、密码修改、余额修改

      4）action类负责响应页面中的点击事件，并反馈结果

四、项目结构截图

五、使用说明

项目采用NetBeans搭建。可以自己下载相应Jar包将文件导入Eclipse中。

六、部分代码
