Java 聚合与继承关系

大家好，我有一个关于Bank.java的问题

我有以下问题：
银行系统需要存储有关银行

账户

和

客户

的信息。银行支持两种不同类型的账户（支票账户和储蓄账户）。所有银行账户都有账户编号、余额和开户日期。为所有帐户定义了两个操作，

makeDeposit（）

和

makedrawing（）

。支票帐户具有支票样式和最低余额的附加属性。储蓄账户具有利率的附加属性和

calculateInterest（）

的操作

所有客户都有

姓名

、

地址

、电话号码。此外，客户可以拥有所需的任意多个帐户。
上述规范已扩展为以下新要求：有两种特殊类型的客户（

个人

和

商业

）。商业客户具有信用评级、联系人和联系人电话的附加属性。个人客户具有

家庭电话

和

工作电话

的属性。此外，扩展模型以显示银行有多个分行，每个账户由一个分行提供服务。当然，每个分行都有很多账户。
创建一个简单的测试程序（无需使用GUI或异常处理，只需使其非常简单）。此测试程序的名称为

Bank.java

，它应该使用上述类

Bank.java

应该声明一个

ArrayList

来保存所有银行账户。测试程序应利用系统能力；以下是演示系统功能的示例操作：

a。在芝加哥分行为商业客户创建支票账户，并将其添加到阵列列表中
B创建一个单独的方法来显示客户信息和帐户余额。代表您在上一步中创建的客户调用该方法。
C将100美元存入您在“a”中创建的帐户，然后显示新信息。
D为某分行的个人客户创建一个初始余额为100美元、利率为10%的储蓄账户，并将其添加到阵列列表中。 E显示储蓄账户信息
F将100美元存入储蓄账户，计算利息，然后显示信息
G执行您选择的其他操作

这是我的代码，除了

Bank.java

类之外，我已经写了所有的东西，我不知道从哪里开始，或者怎么做，请任何人帮助我或者告诉我该怎么做

在这里您可以找到我的代码：
