classes textmessage, videomessage, and voicemessage.

the message class has attributes of account number and price. in addition it has the methods
getinfo(accountnum) and

the subclasses each have one additional attribute of thier own. textmessage has characterlength,
videomessage has messsize and voicemessage has numminutes.

each subclass overrides the methods of the superclass with thier own. no getter or setter methods need to
be documented.

hint: the message class will have a constructor that takes the account number as an argument. each subclass should also have their own constructor which takes their respective additional attribute as an argument; as well as the account number, obviously.
