Where to plug in the factory method in the abstract factory pattern?

Yes it should be perfectly fine to put those method in class pizzaStore as static methods. Generally I consider, putting such factory method in a class based on its return type, and pizzaStore is a good candidate for it.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
