创建一个银行账户的继承层次，表示银行的所有客户的账户。每个客户都能在他们的银行账户存钱，取钱。但是账户可以分为更具体的两种类型，例如，依靠存款生息的存储账户SavingsAccount类，另一种就是信用卡账户CheckingAccount(没有利息但可以透支一定的金额)。每个账户的每次交易都需要存储以方便用来查询。每个客户可以拥有很多不同id的银行账户。
1、题目描述
创建一个银行账户的继承层次，表示银行的所有客户的账户。每个客户都能在他们的银行账户存钱，取钱。但是账户可以分为更具体的两种类型，例如，依靠存款生息的存储账户SavingsAccount类，另一种就是信用卡账户CheckingAccount(没有利息但可以透支一定的金额)。每个账户的每次交易都需要存储以方便用来查询。每个客户可以拥有很多不同id的银行账户。
2、
【任务一】根据设计出的UML图，回答问题
(1). Person和Account之间是什么关系？
(2). Account和Transaction之间是什么关系？
(3). SavingsAccount和CheckingAccount和Account之间是什么关系？
【任务二】根据设计图和运行结果，设计出每个类的代码。测试程序的主要代码已经给出，请补充部分方法。

最后的输出格式和编译器有关，不同编译器最终对齐方式可能有所不同，最终输出格式请自己修改。
