BankWithExceptions

Clone the C# project BankWithExceptions.

This exercise is about throwing and catching exceptions The project contains a class BankAccount. It defines a fairly straightforward bank account, but there are a few restrictions in it (see the code). One restriction is that the balance must not become negative.

The project also contains three additional classes: 

• IllegalInterestRateException
• NegativeAmountException
• WithdrawAmountTooLargeException

They are all exception classes, i.e. they inherit from Exception. The specific purpose of each exception class is described in the code. The BankAccount class already uses the WithdrawAmountToo-LargeException class, to prevent that the balance becomes negative (see the Withdraw method)

1. Modify the code in the BankAccount class, such that the additional exception classes are used properly

2. Update the test code found in InsertCodeHere.cs, such that method calls that could cause an exception to be thrown are enclosed in try-catch blocks

3. Test that the exceptions are thrown and handled properly, by adding some test code that will provoke the exceptions to happen
