这是一个使用io流和swing库制作的可存储的窗口化ATM机程序;臭不要脸的发上来
实现的功能有:1.登录和注册用户(虽然现实中的ATM中没有注册功能)
2.存款
3.取款
4.查询记录,包括存款和取款和转账的记录
5.更改密码
6.退卡
类的构成:1.Test类,实现读取用户文档并更新用户文档的功能;
2.LoginGui类,登录界面,实现登录和注册等功能;
3.Menu类,菜单界面
4.InMoney,OutMoney,Inqury,Transfer类,ChangePassword,分别为存款界面,取款界面,查询界面,转账界面,更改密码界面
5.Account,账户类,实现账户的各种功能,包括存款,取款,转账,更改密码等
项目思路:1.该项目中通过文本来保存用户信息和操作记录,用户信息存储在users.txt中,用户的记录存储在相应用户的用户名.txt中,在程序开始时,调用Test类中的
usesrListRead方法读取users文档,将信息读入程序,得到用户信息,创建用户的List(Tset类中的usersList),并创建用户;
2.首先在登陆界面进行登陆或注册,进行合法性验证,若能成功注册,创建相应的Account类,并创建相应的记录文本,然后要求登录。如果能成功登陆,将Tes
t中的静态变量currentAccount(当前登录的用户)设置为该用户,之后的操作对这个用户进行操作。本程序中
有一个默认用户,id为admin,密码为123456,可以直接登录。记录文本用来存储用户的操作,在后面的每一步操
作中都会通过io流写入记录文本;
3.登陆后弹出菜单,点击按钮弹出相应界面,使用功能后将记录根据文件名存储在用户相应的记录文件中,然后每一次用户状态改变时(使用功能后)都会调
用Test类中的usersListUpdate对用户文档进行更新。这样关闭程序后下次再打开程序时再读取文档就能恢复信息。也就是完成了保存功能。
4.各个界面均是使用java自带的swing库实现的。
注意:1.Test类中使用了很多静态变量来进行全局传值。Test.xxx什么都表示是Test 类中的静态变量。
2.不能同时用read和write对同一个文件进行操作,否则会清空文件 ,应注意
流的关闭

本人是一名大二的学生,目前只学了一学期的java,因此有很多不规范的地方,请见谅。
这个程序技术含量并不高,在计划做的时候觉得很简单,但实际上写的时候,发现有一些细节逻辑比较难以处理和混乱,花费了我一周的时间,其中修复逻辑上的bug花了60%的时间,所以想发出来纪念一下。
我第一次写这么大的java程序,所以可能会有些混乱和有些多余的代码,但我详细的写了注释。希望能帮助到
需要帮助的朋友。若有问题,欢迎交流。
