Hi Guys,
I am trying to finish my design choice and now I am dealing with this part (Extending vs. Modifying)
I'd like to have your comments on this part (by the way I didn't used none of those )
As I understand when we need to have a compelled new entity we will extends but if there is some functionality that is really bound to parent class we need to modify? But I guess I need some academic explanation for it,
Thanks again
