NoServiceChargeChecking : A checking account with no monthly service charge is a
checking account. Therefore, it inherits all the properties of a checking account.
Furthermore, this type of account pays interest, allows the account holder to write
checks, and requires a minimum balance. The named constants, instance variables, and
methods of this class are described in Figure 10-11, which also shows the UML class
diagram of the class NoServiceChargeChecking .
