本人学校在大二时有Java课程设计,本打算在网上找一个简单的银行管理系统借鉴一下,后来得知老师要求要实现可视化,在网上多次查找没有理想的可视化银行管理系统,无奈花费一星期自学了GUI方面的代码,课上老师也没有教过。经过一个多星期的奋战,解决了很多问题,最终完成此系统。闲来无事就想把代码分享出来,供学弟学妹们借鉴,如果觉得有帮助,希望可以点赞,如果经济富裕可以打赏,感激不尽。
(图片为部分运行结果)
代码初期想分为多个类,后来发现跳转界面时会出现很多问题,就把所有可视化代码放在一个类中,数据类单独写出来,应该还是比较精简易懂。其中可视化部分纯手工打造,数据类有所借鉴。运行代码之前需要在eclipse上下载swing插件。
此银行管理系统分为人工服务和ATM服务,功能划分可能不太合理,不过功能应该是很齐全。人工服务可以创建银行卡和登录银行卡。ATM服务可以登录和修改密码。具体功能包括取钱、存钱、查询操作记录。查询操作记录是根据本机时间生成记录。创建银行卡会生成ｔｘｔ文件，信息保存在ｔｘｔ文件中，如果正常使用肯定是不安全的，等以后再完善。
首先是用户信息类
Ａccount.java
package data;

public class Account {
public int money;
public String id;//账号名
public String Name;//姓名
public String PhoneNumber;//手机号
public String IdCard;//身份证
public String password;
Date now=new Date();
Date currentTime;
SimpleDateFormat formatter;
Reader fr;
;
public Account(String id, String password, String money) {//构造方法
this.id = id;
this.password = password;
this.money=Integer.parseInt(money);
}
public void outMoney (int money)throws Exception {//抛出异常，由相关的界面类弹窗处理异常,下面几个方法同理
//如在取钱界面取钱，则会调用此函数，进行try/catch处理，获得这个函数的异常，弹窗说明异常
if (money > this.money) {
throw new Exception("余额不足");
}
if(money<0)
{
throw new Exception("不能取出负数");
}
formatter = new SimpleDateFormat("yy-MM-dd HH:mm:ss");//时间格式
currentTime = new Date();//当前时间
String dateString = formatter.format(currentTime);//处理当前时间格式
Writer fw = new FileWriter(demo1.file);
fw.write(demo1.recordString.append(dateString + "\t" + demo1.currentAccount.id + "\t取出" + money + "元\r\n").toString());//将这次的取钱行为添加到记录文件中
fw.flush();//写进文件
fw.close();
this.money -= money;
demo1.usersListUpdate();//更新用户文档（信息）
}
public void inMoney(int money)throws Exception
{
try {
Writer fw = new FileWriter(demo1.file);
// System.out.println(Test.file);
formatter = new SimpleDateFormat("yy-MM-dd HH:mm:ss");
currentTime=new Date();
String dateString=formatter.format(currentTime);
fw.write(demo1.recordString.append(dateString+"\t"+demo1.currentAccount.id+"\t存入" + money + "元\r\n").toString());
fw.flush();//写进文件
fw.close();
this.money+=money;
demo1.usersListUpdate();//更新当前用户信息
}
catch (Exception e1)
{
throw new Exception("写入记录失败");
}
}
public void ChangePassword(String newPassword)throws Exception
{
if(newPassword.equals(this.password))
{
throw new Exception("原密码和新密码不能一样");
}
else
{
if(newPassword.equals(""))
{
throw new Exception("密码不能为空");
}
}
password=newPassword;
demo1.usersListUpdate();
}
}
然后就是最主要的可视化部分代码,可能有些长,但是都有注释,各个功能模块都有分开写,如果有看不懂可以私聊我.
