I am a computer science student that likes to explore CS-related content and I accidentally stumbled upon your channel. I may say that these 25+ min videos are better structured than all the lectures I have attended at my University. Well done! I am a subscriber now!

This is a great video, you covered the pattern very well. I wanted to add one additional point which you will see in many implementations of this pattern: When you have multiple concrete implementations of a factory, you have the same problem you had when faced with multiple concrete implementations of a product. You want to get the type of product you need, but don't want to get your hands dirty with the business logic involved in creating it. With multiple concrete factories, how can you apply a polymorphic solution for creating the correct type of factory? The answer is a factory of factories. The same way we abstractify the logic for creating products, we can abstractify the logic for creating factories that produce families of products. Let's use your operating system example: You want platform-specific UI's, and have created UI factories for Mac OS, Linux, and Windows. Maybe you also have subclasses of those factories for things like light mode, dark mode, accessibility mode, etc. When the program begins, you detect the operating system and graphical settings, and send those details to your factory of UI factories. You are given back the correct concrete UI factory implementation specific to your needs, and can start producing UI elements. Without this extra polymorphic layer, you may be faced with the same problem that the factory pattern was devised to solve.

You're really onto something with your design patterns series here. Keep on keeping on. I especially appreciate the fact that you compare the implementation to real world applications. For a follow up series I'd suggest revisiting the patterns after a while and focusing on the comments, most common questions, misconceptions, etc.

Thank you Chris for this series of video, In this chapter in the book, they make an example using something like an IngredientFactory, something like that i was really impressed because the "Ingredient" receives a concrete factory by passing it in the constructor. That way the Pizza factory was able to cook itself according to the contract that the concrete factory already implemented. I think that specific part of the example from the book was really awesome and i recommend showing that part. Anyway, really thanks for sharing your knowledge on design patterns you're really good at explaining.

I think the concept of Factories finally makes sense to me now. I can see how the process of creation of an object has been abstracted away. However, contrary to what I've read somewhere that it is meant to avoid the 'new' keyword, your explanation makes much more sense. I can see now how one might want to avoid 'new' keyword unnecessarily in order to have dynamic object creation code. Still, it is necessary to understand that you cannot completely avoid the 'new' keyword as the concrete factories themselves must be created at some point in the code. I think the key power of factories is their ability to provide a means of creating and using 'wishful' objects of classes that don't even yet exist in the code. Thanks a lot man.

Thanks for the awesome videos! I think the main difference between Factory Method and Abstract Factory is that Factory Method relies on inheritance and let subclass decides how to create object through the factory method(s), whereas Abstract Factory uses composition, client gets an object that implements abstract factory interface and uses that object to create items. Abstract Factory is at a higher level since it is an object, while factory method is only a method.
