Add a toString method to the BankAccount class from the previous exercise. Your method should return a string that contains the account’s name and balance separated by a comma and space. For example, if an account object named yana has the name "Yana" and a balance of 3.03, the call yana.toString() should return the string "Yana, $3.03".

Data from Previous Exercise

Suppose the following BankAccount class has been created:

Add a field to the BankAccount class named transactionFee for a real number representing an amount of money to deduct every time the user withdraws money. The default value is $0.00, but the client can change the value. Deduct the transaction fee money during every withdraw call (but not from deposits). Make sure that the balance cannot go negative during a withdrawal. If the withdrawal (amount plus transaction fee) would cause it to become negative, don’t modify the balance at all.
