5.2 源代码说明 5.2.1 源代码中自定义类的说明： 代码中出现的Account类、MainFrame类、Load类、Take类、Input类、Setpew类和Display类都继承了Java类JFrame。 （1）Class Accout创建客户，初始化客户信息功能以及保存客户信息，例如：卡号、密码、原有余额、取款后卡里的余额以及存款后卡里的余额。此类包含的成员有：成员变量account、count、password和方法构造方法Account()。 面向对象课程设计ATM柜员机模拟程序 22 （2）Class MainFrame构造主界面，提供业务选择，让用户可以在这个界面选择存款、取款、查询余额、修改密码。它包含的成员有：构造方法MainFrame()和初始化主界面的方法 initComponents()以及成员变量checked、cunkuan、quite、qukuan、reset。 （3）Class Load 实现登录功能和登录界面，如果用户名和密码匹配就可以登录到主界面否则报错。它的成员有：Jpassword、accountnum、committ、JL1、JL2和构造方法Load()和初始化方法initComponents()。 （4）Class Take实现取款功能，按返回键返回主界面，按清除键可以删除输入数字，并且取出的金额必须是100的整数倍，一次取出的金额不能超过5000，取完款后可以显示余额。该类的成员有：back、clear、commit、quite、JL1、JT1和构造方法Take()和初始化的initComponents()。 （5）Class input实现存款功能，存款的金额必须是100的整数倍，否则报错提示重新输入。成员有：clear、commit、jL1、jT1、str以及构造函数Inputhe（）和初始化方法initComponents() （6）Class Display功能为显示当前余额，在显示余额时JTextField的内容不可以编辑，成员有：成员变量back、jL1、quit、qukuan和构造方法Display()和方法数set(String str)和初始化的方法initComponents()。 （7）class Setpw创建此类是为了实现修改密码的功能，设置的密码必须是六位以上的字符，并且所设置的密码不能是同一个字符组成，否则报错。成员有：成员变量commit、commitpw、jPwcommit、jPwnew、jPwold、newpw、oldpw、quit和构造方法Setpw()和初始化方法initComponents()。 5.2.2源代码中的事件监听器 （1） MainFrame类的监听器 在该
