Requirement: In this assignment, you are going to handle exceptional cases in the bank account class for foreign currencies. In the attached files, source codes for ForeignCurrencyAccount and Account classes are given. There is also Test3.java and Transaction.java that run operations on the bank accounts. Please complete the implementation of ForeignCurrencyAccount and Account classes, so that following exceptional cases are handled by them. Do not add new attributes or methods to ForeignCurrencyAccount and Account classes. Just add code to throw exceptions or handle exceptions. Exceptional cases: 1. Whenever a transaction amount given to "withdraw" method is greater than account's balance, an exception of class InsufficientFundsException should be thrown. 2. Whenever InsufficientFundsException is caught within buyForeignCurrency or sellForeignCurrency methods, an Exception should be thrown with description "Foreign currency buy/sell transaction failed because of insufficient funds". 3. Whenever setCurrencyCode method is called with a different currency code than the account's currency code and account has non-zero balance, an Exception should be thrown with description "Currency code cannot be changed for an account that has balance". 4. Whenever dailyExchangeRate is zero and a method that uses dailyExchangeRate (for example, convertToCAD method) is called, an Exception should be thrown with description "Daily exchange rate not set".
