ATM标准管理系统java窗口界面.doc

BAM银行账户管理系统（ATM管理系统）本系统采取JAVA语言并在eclipse环境下编写测试完成，包含类概念，和面向对象几大特征（继承，封装，多态，抽象），也有异常处理机制，采取集合（愈加好）存放账户数据，基础能够满足大多数BAM系统相关实现，且代码内标注大量注释，读者能够很轻松地了解相关逻辑，大家能够快乐参考。系统介绍：特点：采取窗口界面风格，而不是传统命令行、控制台运作模式1、JAVA类面相对象应用，拥有异常处理机制，不会因为输入错误而造成程序瓦解2、关键有7个类，即Account（账户类）SaveAccount（储蓄账户类）：不能透支CreditAccount（信用账户类）：能够透支Bank（银行类）ATMOpenAccountFrame（开户窗口页面）ATMLoginFrame（登录窗口页面）ATMMainFrame（操作窗口页面） 带有完善相关信息提醒弹出窗口 见下面截图 类具体属性级行为见代码 3、各个类之间相互关系，包含继承、封装、多态、抽象，在多态中又包含重载和重 写，请读者注意相关联络（关注注释） 4、能够实现数据保留功效，数据将保留在文件中（即当你注册了一个账户，下次再登 陆系统时，能够实现和上次最终操作相衔接） 5、账户号自动生成，比较符合现实 6、关键功效有：1.开户 2.查询账户余额 3.存款 4.取款 5.转账（一个账户到另一个账户）等 7、运行时界面简示1.初始界面（账户登录） 2.账户登录后界面 3.相关信息提醒一览（只列举一部分）1、查询：2、存款： 3、取款： 4、转账： 4、用户开户界面：注意事项：1、本系统采取编程环境是JDK1.7，jer7。所以，运行代码需要保持电脑上所装JDK为1.7以上版本，如有报错，只需换个高一点版本即可。注意：第一次装JDK，要配置环境变量（请查阅相关资料，比较简单）2、本系统代码包含到包，所以假如报名不一致就会报错，处理方法：修改一下包名即可3、提议把各个类写在同一个包下面，且每一个类单独写一个java文件，以下图：4、在运行程序前，需要在项目下面新建一个account.txt（用来保留数据）文件（如上图），并在其中写入最少一个账户信息，（以下图，其中每项代表意思，请读者参考代码内注释），不然在初始化时候会因为找不到账户信息，从而产生异常。系统源码：Account类package
