可以采用两种方法配置数据库:该系统登录初始账号为admin,初始密码为admin。
-------------------------------1.利用SQL语句创建数据库本例使用的后端数据库是Microsoft公司的SQLServer2000,需要配置数据库和并创建表格。
步骤如下:(1)打开SQLServer的企业管理器,并依次打开左边TreeView(树型视图)中的节点:【控制台根目录】->【MicrosoftSQLServers】->【SQLServer组】->【(Local)】->【数据库】。
(2)鼠标右键单击“数据库”节点,在弹出的菜单中选择“新建数据库”。
(3)在弹出的对话框中输入数据库名“stu”,单击“确认”按钮,数据库建立成功。
(4)关闭企业管理器,打开SQLServer查询分析器,选择stu数据库(若设置了SQLServer安全性,则还需要输入用户和密码登录到SQLServer)。
(5)在查询分析器中输入如下代码建立数据表结构。
可以直接导入“data”目录下的stu.sql文件运行。

BankAccountManagementSystem银行账户管理子系统简称BAMS这是一个基于C/S结构的银行账户在线管理系统,用户可以通过ATM终端界面来操作自己的银行账户.ATM1:要求1:封装一个Account类-业务数据写一个账户类(Account),属性并且完全封装(注意:要辨别每个属性的set/get方法是否需要公开):id:账户号码长整数(Long)password:账户密码字符串类型(String)name:真实姓名字符串类型(String)personId:身份证号码字符串类型(String)email:客户的电子邮箱字符串类型(String)balance:账户余额双精度(double)方法:deposit:存款方法,参数类型:double,返回类型:Accountwithdraw:取款方法,参数类型:double,返回类型:Account构造方法:有参和无参,有参构造方法用于设置必要的属性ATM2:要求1:完成以下两种账户类型的编码。
银行的客户分为两大类:储蓄账户(SavingAccount)和信用账户(CreditAccount),两种的账户类型的区别在于:储蓄账户不允许透支,而信用账户可以透支,并在用户在满足银行条件的情况下允许用户调整自己的透支额度.注意:1、CreditAccount需要多一个属性ceiling透支额度;
2、CreditAccount需要覆盖(重写)Account中的取款方式withdraw()。
要求2:完成Bank类的编码。
属性:1.当前所有的账户对象的信息,存放在数组中:Account[].2.当前账户数量index.方法:1. 用户开户(register)参数列表:Long账号,String密码,String确认密码,String姓名,String身份证号码,String邮箱,int账户类型;
(Longid,Stringpassword,Stringrepassword,Stringname,StringpersonID,Stringemail,inttype)返回类型:Account项目需求规定账户类型:0–储蓄账户1–信用账户2–可贷款储蓄账户3–可贷款信用账户2. 用户登录(login)参数列表:Long账号,String密码;
(Longid,Stringpassword)返回类型:Account3. 用户存款(deposit)参数列表:Long账号,double存款金额;
(Longid,doublemoney)返回类型:Account4. 用户取款(withdraw)参数列表:Long账号,String密码,double取款金额;
(Longid,Stringpassword,doublemoney)返回类型:Account5. 设置透支额度(updateCeiling)参数列表:Long账号,String密码,double透支额度金额;
(Longid,Stringpassword,doublemoney)返回类型:Account提示:这个方法需要验证账户是否是信用账户6. 转账功能(transfer)参数:from转出账户,passwordFrom转出账号的密码,to转入账户,money转账的金额(Longfrom,StringpasswordFrom,Longto,doublemoney)返回值:boolean要求3:另外,请为Bank类添加几个统计方法1.统计银行所有账户余额总数2.统计所有信用账户透支额度总数要求4:编写测试类写个测试类,测试以上代码能否正常工作。
要求5:覆盖toString方法查看对象的内容。
ATM3:要求1:让银行来提供账号(id)的生成修改Account类和Bank类,银行用户的账号(id)应是自动生成的,初始值为:862150212013020001(国家+邮编+年+月+序号)。
比如:第一个开户的账号为862150212013020001,第二开户的账号为862150212013020002…依此类推.要求2:修改存款和取款方法对于Account类中的存款方法和取款方法进行修改.存款方法:改为不允许子类修改取款方法:改为抽象方法,便于在子类中去覆盖(重写)要求3:单例将Bank类作成单例。
提醒:一定要理解使用单例模式的原理。
ATM4:要求1:新增一个贷款功能为了满足业务发展的需求,银行需要为用户提供贷款的功能,来满足更多的用户需求。
抽象出一个贷款功能的接口:Loanable该接口具有以下功能:a) 贷款(requestLoan)参数:money贷款金额返回类型:Accountb) 还贷(payLoan)参数:money还贷款金额返回类型:Account提醒:一定要理解抽象接口的原理和真实含义。
要求2:新增两种的新的账户类型为了满足业务发展的需求,新增两种具有贷款功能的账户类型:可以贷款不可以透支账户和可以贷款可以透支账户;
为SavingAccount和CreditAccount各自添加一个子类LoanSavingAccount类和LoanCreditAccount类,同时让两个新增的子类都必须要实现Loanable接口。
为了表示某个贷款账户的贷款金额,需要为所有的可贷款账户提供一个能记录贷款金额,所以要为CreditAccount类整一个普通的成员属性loanAmount,为长整形(long)。
说明1:LoanSavingAccount类表示该账户可以贷款,不可以透支;
LoanCreditAccount类表示该账户可以贷款,可以透支。
说明2:贷款和透支是不一样的,透支指的是账户余额小于0,而贷款用户需要一个贷款额的属性.在ATM机上,用户可以选择贷款,也可以选择还贷款,而还贷款就是要把账户余额上的资金转到贷款额上例如:用户余额10000元,贷款额100000元,用户可以选择还款5000元,则用户余额变为5000,贷款额变为95000元.要求3:为Bank类添加三个新方法a) 贷款(requestLoan)参数:id账户,money贷款金额(Longid,doublemoney)返回类型:Accountb) 还贷款(requestLoan)参数:id账户,money还贷款金额(Longid,doublemoney)返回类型:Accountc) 统计所有账户贷款的总额(totoal)参数:无返回类型:doubleATM5:要求1:修写Bank类,采用集合的方式来管理多个Account对象注意:通过分析每种集合的具体功能和特性后,选择合适的集合类型实现该功能。
要求2:为Bank类添加一个方法,能够打印所有用户的总资产排名(提高部分)说明:1)、一个用户可能会有多个账号,以身份证号为准.2)、总资产指多个账户余额的总和,不需要考虑贷款账户的贷ATM6:Exception要求1:为ATM增加业务异常类:ATMException:ATM业务异常基类。
BalanceNotEnoughException:用于取钱的时候余额不足的情况(包括账户余额超过透支额的情况)RegisterException:用于开户异常的情况,例如密码两次输入不一致等情况LoginException:用户登录异常的情况,例如id错误,密码错误LoanException:贷款额不能为负数,如果用户试图将贷款额置为负数,则会抛出这个异常注意:在此异常的基础也可以继续扩展适合业务的异常类。
ATM7:SwingGUI开发第一步部分:为ATM项目添加用户客户端操作界面需要以下几个类:1) ATMClient:其中会包含一个Frame,这是用户主界面.2) MainPanel:主界面,用户可以选择开户或者登录3) RegisterPanel:用户开户具体用到的界面4) LoginPanel:用户登录需要的界面5) BusinessPanel:界面上会显示账户的功能,至少包括存款\取款\对于可透支的用户,允许用户修改透支额度\对于贷款用户,允许用户贷款和还贷款\转账。
第二步部分:为用户客户端操作界面添加事件处理要求:在开户或者登录之后都会跳到BusinessPanel,而用户点击了交易之后,界面停留在BusinessPanel要随时注意在BusinessPanel上根据数据的变化更新显示信息。
ATM8:I/O&File项目详细内容介绍1、 分析:将账户对象保存文件中,前期为新的账户对象分配id的做法(使用static特性)不再合适现今业务需求,也应相应的改变。
解决方案:将下一个可用的id存放在文件中,每创建一个新对象的时候都会读取这个文件,获得新对象的id,并且修改文件中的id,使其加1后,再保存到文件中。
2、 修改Bank类中各个业务方法分析:要将账户信息全部保存到文件中,然后再从文件读取到内存中进行业务操作,而后再将处理完的业务对象重新保存到文件中永久保存起来。
解决方案:1)采用对象序列化和反序列化技术。
2)将全部账户信息采用对象序列化的方式存放在文件中。
提示:1) 使用文件来保存各种账户的信息,将注册、存款、取款、转账、修改之后的信息要及时的保存到文件中,时刻保证内存和文件中数据的一致性。
2) 采用何种存放方式,自由发挥决定。
ATM9:NetWork分析:在现有的ATM中,用户是通过界面直接访问Bank对象,这种方式不符合业务需求,因为银行后台是受保护的绝对安全的业务操作,所以将其改为C/S结构,由界面充当客户端,通过TCP协议访问服务器端的核心业务对象(Bank对象).解决方案:1) 多线程技术2) 网络编程技术3) 需要完成服务端的编程,负责完成接收客户端的请求和相关业务处理。
注意:如何保证多个客户端同时登陆,并且保证业务数据在冲突的情况下,不能受到破坏。
提示:客户端和服务器端需要通过对象(TO)来传递信息,,这里会使用对象序列化技术.

在日常工作中,钉钉打卡成了我生活中不可或缺的一部分。然而,有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚,我总是得牢记打开钉钉应用,点击"工作台",再找到"考勤打卡"进行签到。有时候因为工作忙碌,会忘记打卡,导致考勤异常,影响当月的工作评价。而且,由于我使用的是苹果手机,有时候系统更新后,钉钉的某些功能会出现异常,使得打卡变得更加麻烦。 另外,我的家人使用的是安卓手机,他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说,每次打卡都是一次挑战。他们总是担心自己会操作失误,导致打卡失败。 为了解决这些烦恼,我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习,我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
