银行综合业务平台业务需求
1.首页
---------------银行综合业务平台-------------------
1开户 2登录 3、退出
------------------------------------------------------------
说明：还没有账号的用户需要先开户，才能登录
2.开户业务
--------------------开户业务-------------------------
---自动生成账号
用户名：（中文姓名）
密码：
确认密码：
联系电话：
开户金额：
------------------------------------------------------------
说明：密码要求是6位数字，联系电话符合电话号码要求，开户金额为数值
3.登录
--------------------- 用户登录 ---------------------
账号：
密码：
-----------------------------------------------------------
说明：当用户开户成功就可以通过账号和密码进行登录了，登录后会打开个人银行业务菜单
4.----------------------个人银行业务菜单--------------------------
1 存款 2 取款 3 查询余额
4 转账 5 修改密码 6 交易记录查询
7 注销登录
--------------------------------------------------------------------------
根据以上需求，实现各业务编码
另要求：1所有开户信息写入1个文件，登录时需要读取文件用户信息验证登录
2.为每个开户账户生成一个以账户命名的文件，记录该账户交易记录
2 业务操作记录日志，写入日志文件
////////////////////////////////////////////////////////////////////////////////////////////////////
提示：
1 基本信息类设计：账户类（账号，密码，用户名，电话，余额，状态）
交易记录类（账号，交易类型，交易时间，交易金额）
操作日志类（账号，操作类型，操作时间）
2 业务管理类设计
定义账户类和交易记录类集合，供读写文件用
