HI all
I want to ask, there were an example on chapter abstract class at project
MyOnlineShopUsingAbstractClass, it's quite same on the previous chapter on
chapter Inheritance at projectmyOnlineShop. I want to ask, when should we use
abstract class and abstract method instead of override and inheritance?what are
the benefit using abstract class and abstract method while the same problem
could fix using inheritance and override?I'm asking because there were two
similiar project example and each of them using different way to process. Hope
anyone can help
Thanks
Hendra
