大家好我有一個關於Bank.java聚合和繼承關係
的問題，我有這樣的問題：
銀行系統需要存儲有關銀行Accounts和Customers信息。銀行支持兩種不同類型的賬戶（檢查和儲蓄）。所有銀行賬戶都有賬戶Number，餘額和date opened。針對所有帳戶定義了兩項操作，分別爲makeDeposit()和makeWithdrawal()。支票帳戶有額外的檢查風格和最小余額屬性。儲蓄賬戶有額外的利率屬性和calculateInterest()的操作。
所有客戶都有name，address和phone number。另外，客戶可以擁有他需要的賬戶數量。
以上規格已經擴展了新的要求如下：有兩種特殊類型的客戶（Personal和Commercial）。商業客戶具有額外的信用評級，聯繫人和聯繫人電話屬性。個人客戶的屬性爲home phone和work phone。此外，擴大模型以顯示該銀行有多個分行，並且每個賬戶由一個分行提供服務。當然，每個分支都有很多賬戶。
創建一個簡單的測試程序（不需要使用GUI或異常處理，只需要簡單）。這個測試程序的名稱是Bank.java，它應該使用上面的類。 Bank.java應聲明ArrayList持有所有銀行帳戶。測試程序應該利用系統功能;以下是演示系統功能的示例操作：
a。爲芝加哥分行的商業客戶創建一個支票帳戶，並將其添加到數組列表
b。創建一個單獨的方法來顯示客戶信息和賬戶餘額。代表您在上一步中創建的客戶調用方法。
c。將$ 100存入您在'a'中創建的帳戶，然後顯示新信息。 d。爲初始餘額爲100美元，利率爲10％的某個分行中的某個客戶創建一個儲蓄賬戶，並將其添加到數組列表中。 e。顯示儲蓄賬戶信息
f。向儲蓄賬戶存入100美元存款，計算利息，然後顯示信息
g。實施您選擇的其他操作！
這是我的代碼我已經寫了除了Bank.java類以外的所有東西，我不知道從哪裏開始或如何去做，請任何人幫助我或讓我知道該怎麼做。
在這裏你可以找到我的代碼：

由於各種原因，很多人不會遵循鏈接。通過不包括你的代碼，你正在減少找到你的問題的答案的機會。您也可能會收到反對票。 – MikeT
爲什麼你不能嘗試編碼任何你想完成的事情，並提出問題，如果你卡住了 – prasanth
我確實把我的代碼。 – Skarali
