java bank项目

精选的文库基于Java的实战-bank项目实验标题1:建立简易银行套件实验目的：Java语言中面向对象的封装和构造函数的创建和使用。实验说明：在本练习中，您将创建帐户类的简单版本。将此源文件放入banking包中。在创建单个帐户的基本软件包中，创建了测试程序TestBanking。此测试程序初始化帐户馀额，并执行一些简单的处理。最后，测试过程显示了帐户的最终馀额。提示：1.创建banking软件包2.在banking包下创建Account类。此类必须实现上述UML方框图的模型。A.声明维护银行帐户当前(或立即)馀额的个人对象属性balance。B.声明具有一个参数(init_balance)的公共构造函数，该参数为balance属性赋值。C.声明geBalance，这是用于获取常规馀额的公共方法。D.声明deposit，这是增加当前馀额金额的公用方法。E.声明公共方法withdraw，以从当前馀额中减去金额。3.打开TestBanking.java文件，按照提示完成合成，然后编译TestBanking.java文件。4.运行TestBanking类。可以查看以下输出结果：使用500.00 balance创建帐户Withdraw 150.00Deposit 22.50Withdraw 47.62The account has a balance of 324.88/TestBanking.java文件/* this class creates the program to test the banking classes。* it creates a new bank，sets the customer，* and performs a series of transactions with the account object。*/打包测试；Import banking。*；Public class test bankingpublic static void main(stringargs)帐户帐户/create an account that can has a 500.00 balance。system . out . print ln( creating an account with a 500.00 balance . )；/代码system . out . print ln( with draw 150.00 )；/代码system . out . print ln( deposit 22.50 )；/代码system . out . print ln( with draw 47.62 )；/代码/print out the final account balancesystem . out . print ln( the account has a balance of account . get balance()；基于Java的实战-bank项目实验标题2:扩展银行项目并添加客户类。Customer类包含一个Account对象。实验目的：使用引用类型的成员变量。杰西：1.在banking包下创建Customer类。此类必须实现上述UML图的模型。A.声明三个专用对象属性：firstName、lastName和account。B.声明具有两个参数(f和l)的公共构造函数以表示对象的属性C.声明两个公共存取器以访问对象属性时，将返回getFirstName和getLastName方法返回到属性。D.声明setAccount方法以向Account属性赋值。E.声明getAccount方法以获取Account属性。2.在exercise2主目录中编译并运行此TestBanking程序。应显示以下输出：Creating the customer Jane Smith。使用500.00 balance创建帐户。Withdraw 150.00Deposit 22.50Withdraw 47.62Customer Smith，Jane has a balance of 324.88/TestBanking.java文件/* this class creates the program to test the banking classes。* it creates a new bank，sets the customer，* and performs a series of transactions with the account object。*/Import banking。*；Public class test bankingpublic static void main(stringargs)客户客户帐户帐户/create an account that can has a 500.00 balance。system . out . print ln( creating the customer Jane Smith . )；/代码system . out . print ln( creating her account with a 500.00 balance . )；/代码system . out . print ln( with draw 150.00 )；/代码system . out . print ln( deposit 22.50 )；/代码system . out . print ln( with draw 47.62 )；/代码/print out the final account balancesystem . out . print ln( customer customer . get last name()， customer.getFirstName()has a balance of account . get balance()；基于Java的实战-bank项目实验标题3:修改Withdraw方法以返回一个布尔值，指示事务是否成功。实验目的：使用具有返回值的方法。杰西：1.修改Account类A.修改deposit方法，返回true(表示所有存款都成功)。B.修改withdraw方法以查看提取数是否大于馀额。如果Amt小于balance，则从馀额中减去提取数，并返回true。否则，馀额不会返回false。2.在exercise3主目录中编译并运行TestBanking程序时，将显示以下输出：Creating the customer Jane Smith。creating her account with a 500.00 balance . with draw 150.003360 truedeposit 22.503360 true with draw 47.62: true with draw 400.003360 falseCustomer Smith，Jane has a balance of 324.88/TestBanking.java文件/* this class creates the program to test the banking classes。* it creates a new bank，sets the customer，* and performs a series of transactions with the account object。*/Import banking。*；Public class test bankingpublic static void main(stringargs)客户客户帐户帐户/create an account that can has a 500.00 balance。system . out . print ln( creating the customer Jane Smith . )；/代码system . out . print ln( creating her account with a 500.00 balance . )；/代码/perform some account transactionssystem . out . print ln( with draw 150.003360 account . withdraw(150.00)system . out . print ln( deposit 22.503360 account . deposit(22.50)；system . out . print ln( with draw 47.62: account . withdraw(47.62)system . out . print ln( with draw 400.003360 account . withdraw(400.00)/print out the final account balancesystem . out . print ln( customer customer . get last name()， customer.getFirstName()has a balance of account . get balance()；基于Java的实战-bank项目实验标题4:阵列体现了银行和客户之间的多种关系。实验目的：类使用数组作为模拟集合操作。提示：对于银行，可以添加银行类。银行对象跟踪自身和客户之间的关系。此集合关系是使用Customer对象的数组实现的。还必须保留整数属性，以跟踪当前有多少客户在银线上。创建银行组类B.向Bank类添加两个属性：customers(Customer对象的数组)和numberOfCustomers(跟踪以下customers数组索引的整数)C.添加公用构造函数，以使用适当的最大大小(至少5个)初始化customers数组。D.添加addCustomer方法。此方法需要根据参数(姓，名)配置新客户然后，将对象放入customer数组中。此外，numberofCustomers属性值应加上1。E.添加返回numberofCustomers属性值的getNumOfCustomers访问方法。F.添加getCustomer方法。返回与给定index参数相关联的客户。G.编译并运行TestBanking程序。可以查看以下输出结果：Customer 1 is Simms，JaneCustomer 2 is Bryant，OwenCustomer 3 is Soley，TimCustomer 4 is Soley，Maria/TestBanking.java文件/* this class creates the program to test the banking classes。* it creates a new bank，sets the customer，* and performs a se
