Java实现简单银行ATM功能
本文实例为大家分享了Java实现简单银行ATM功能的具体代码，供大家参考，具体内容如下
实现功能
1、用户需要通过输入银行卡号和密码才能进入ATM系统
2、用户可以在ATM中实现取款、存款、转账、余额查询、退出系统等功能
简单分析
1、创建User类(cardNo,identity,phone,username,password,balance(余额))
2、创建Bank类，主要实现初始化用户、用户登录、显示菜单、取款、存款、转账、余额查询、退出系统等功能。
代码实现

publicclassUser{
privateStringusername;
privateintpassword;
privateStringcardNo;
privateStringidentity;
