Java基于控制台界面实现ATM系统（atm柜员机模拟系统java课程设计）

本文实例为大家分享了java实现ATM系统的具体代码，供大家参考，具体内容如下

这应该算最基础的Javase项目了，但其中逻辑还是得想想的。

功能还算完善，只是对输入数据的校验没做全，之后做web时再加上。

没有数据库。

完整代码在最后。

流程图

登录

想模拟提款机插卡登录的，因此没做注册账号的功能，手动先塞了三个账号。有三次输入密码机会。

查询

取款

存款

转账

修改密码

退出

代码

文件结构

下面两个类复制过去放到ATM文件夹下就能运行。

package ATM;

private String cardID;

private String username;
