Java实习报告ATM自动柜员机

JAVA一、实习目的

1、将所学知识进行一种系统的联络。2、培养学生分析问题和处理问题的能力，为学生提供了独立实践的机会。3、理论联络实际，巩固所学知识，提高学生处理处理实际问题的能力。4、深入培养学生面向对象程序设计的思想。5、将所学知识与社会实际现象相联络，使学生更清晰java的用途。二、实习地点安康学院经济与管理系7405试验室三、实习内容1、题目ATM自动柜员机模拟程序2、功能简介ATM自动柜员机包括如下操作内容：修改账号密码、余额查询、ATM取款、ATM存款四、实习过程1、选题阶段根据自己的学习状况和个人爱好选择要设计的内容，通过反复判断抉择我最终的实习项目选择是：ATM自动柜员机模拟程序2、分析题目规定的功能阶段针对题目和现实状况列出程序的功能，然后对每一种功能进行分析，画出草图，并列出每一种功能能的要账号登陆：银行账号和初始密码为“123456”修改密码：旧密码等于原密码，新密码必须不不不小于6位，并且新密码两次输入的一致查询余额：初始余额为10000元ATM取款：取款的金额必须为100的倍数，不不小于5000元，并且不能不小于余额ATM存款：存款的金额不能为负数3、制定方案阶段画出每一种功能模块的草图1）
