Yes, I don't know either.  I got this assignment for my homework, and
in UML diagram class ShoppingCart has method buy(), and the class
Buyer doesn't have any methods, only attribute ShoppingCart, and I
must simulate/implement online shopping.  In my world buyers buy too,
just wanna check with somebody with more experience.  :)

Thank you both.

[Newbie] design question

2007-05-12 Thread idaku2 
Hi all

Suppose I have class ShoppingCart which has one method called buy(),
and class Buyer who has one reference to ShoppingCart...  Can I also
have method buy() in class Buyer, which will then called
ShoppingCard.buy(), and also do some other stuff?  Is this legal
design pattern, have methods with same name?

Thanks in advance.
