ATM柜员机模拟程序摘要使用图形用户界面。

当输入给定的卡号和密码（初始卡号为123456和密码为123456）时，系统能登录ATM柜员机系统，用户可以按照以下规则进行：查询余额：初始余额为50000元ATM取款：每次取款金额为100的倍数，总额不超过5000元，支取金额不允许透支。

ATM存款：不能出现负存款。

修改密码：只有旧密码正确，新密码符合要求，且两次输入相同的情况下才可以成功修改密码。

我所设计的ATM柜员机主要是由登录页面模块还由选择服务模块组成，其中选择服务模块又由取款模块、查询余额模块、修改密码模块、退卡模块组成。

一个系统界面的好坏直接影响到用户的操作，界面设计要求样式美观、简单明了、方便易操作。

我设计的界面主要分为窗体、菜单、按钮和文本输入框几个部分，分别执行相应的操作。

When the input given card number and password (initial card number for 123456 and password for 123456), the system can login ATM machines system, users can according to the following rules:Inquires the balance: initial balance is 50000 yuan ATM withdrawals: every time a multiple of the amount of, the total will not more than 5000 yuan, the amount of withdrawals allows no overdraft.ATM deposits: can't negative deposits.Change the password: only the correct password is old, the new password accords with a requirement, and two enter the same case can be modified successfully password.!I designed by ATM machines is mainly composed of the login page module by choice service module is, selecting the service module by withdrawals and module, inquires module, modify the password balance module, return card modules.

学院进行了此项课程设计教学活动，此次课程设计的主要任务是为了训练同学们利用所学知识，开发小型应用系统，掌握运用JAVA语言编写调试应用系统程序，训练独立开发应用系统，进行数据处理的综合能力。

针对这次课程设计任务，我对于给定的题目，进行了详细分析，理清了思路，弄明白了应该分几步走，每一步应该怎么走。

顺利完成了课程设计任务。

项目任务要求：1、程序分为两部分：管理端和客户端。

2、管理端负责管理所有的银行卡，管理员（省略身份验证）可以增加和删除银行卡。

（1）每张银行卡由卡号唯一标识，卡号由12位阿拉伯数字组成；（2）新增的银行卡密码均为“123456”，卡内金额均为0元；（3）只有管理员增加的银行卡才能登陆客户端；（4）删除后的银行卡将不能再登陆客户端。

Java银行账户管理系统代码简介银行账户管理系统是一个用于管理银行客户账户的软件系统。

该系统可以实现客户开户、存款、取款、转账等基本功能，同时提供了查询账户余额、查询交易记录等附加功能，便于客户管理自己的资金。

功能模块客户管理模块这个模块包括客户信息的增删改查功能。

系统可以记录客户的姓名、身份证号、手机号等基本信息。

账户管理模块这个模块包括账户的开户、销户、存款、取款、转账等功能。

它的各种按钮的事件和功能可以简单的模拟ATM柜员机的要求。

2系统需求分析2.1功能需求分析主要功能如下所述：要求使用图形用户界面。

当输入给定的卡号和密码（初始卡号为000000和密码为123456）时，系统能登录ATM柜员机系统，用户可以按照以下规则进行：■查询余额：初始余额为50000元•ATM取款：每次取款金额为100的倍数，总额不超过5000元，支取金额不允许透支。

■ATM存款：不能出现负存款。

■修改密码：只有旧密码正确，新密码符合要求，且两次输入相同的情况下才可以成功修改密码。

2.2其他需求分析（1）性能描述实时性好、灵活性强、易于不同年龄阶段的人操作。

（2）设计约束开发工具：JCratorProV3.5.0运行环境：Windows2000以上能实现用户所定义的各项需求。

（3）界面要求以Windows窗口形式显示，标题栏为ATM柜员机名称，右上角有最小化按钮、最大化按钮、关闭按钮，不同的窗口中有不同的按钮和选择菜单。

3系统设计3・1总体设计我所设计的ATM柜员机主要是由登录页面模块还由选择服务模块组成，其中选择服务模块又由取款模块、查询余额模块、修改密码模块、退卡模块组成。

其功能结构图如下所示：图1ATM功能结构示意图3・2ATM柜员机界面设计一个系统界面的好坏直接影响到用户的操作，界面设计要求样式美观、简单明了、方便易操作。

原创Java银行账户管理系统代码
简介
本文档将介绍一个原创的Java银行账户管理系统代码。

该代码用于模拟一个简单的银行账户管理系统，包括账户的创建、存款、取款、查询余额等功能。

功能列表
•创建账户：根据用户输入的账户信息，创建新的银行账户。

•存款：将用户输入的金额存入指定账户。

•取款：从指定账户中取出用户指定的金额。

•查询余额：根据用户输入的账户信息，查询指定账户的余额。

开发工具和环境
•开发语言：Java
•开发环境：Eclipse IDE
•JDK版本：Java SE 8
代码实现
下面是代码的具体实现。

```java import java.util.HashMap; import java.util.Map; import java.util.Scanner;
public class BankAccountManagementSystem {
private static Map<String, Double> accountMap = new HashMap<>();
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
boolean running = true;
while (running) {
System.out.println(\。
