Create an inheritance hierarchy that a bank might use to represent customers’ bank accounts.  All customers at this back can deposit (i.e. credit) money into their accounts and withdraw (i.e. debit) money from their accounts.  More specific types of accounts also exist.  Savings accounts, for instance, earn interest on the money they hold.  Checking accounts, on the other hand, charge a fee per transaction.
