Two Classes, One table

[Rex Madden]

I have a table called CUSTOMER which I would like to have broken down
into two classes: 1 called Customer and 1 called Address.  The Customer
class would obviously hold the basic customer info, and then the Address
class would hold info for the user's billing address and the user's
shipping address.  But all of this would be on 1 table.  Is there any
way to map this?  Or am I better off having an address table?
 
Thanks,
Rex
