What is the Factory Pattern? | Software Design Principles
HTML-код
- Опубликовано: 4 авг 2024
- The factory pattern is one of the most popular design patterns. Factories help us delegate the responsibility of object creation to a dedicated object. Through polymorphism, we can further enhance this pattern. In this video, I define and discuss the utility of the Factory pattern and how it applies to software design. I also demonstrate the pattern through an easy to follow example.

The factory pattern helps us to NOT repeat logic all over the place - there is one and only one place to create a new object. So if that new object some day needs new parameters or less parameters, then we don't need to change our code all over the place. We need to only update the Factory where the new object is created.
nice.
Why doesn't this have more views? That's premium content.
Thank you so much for your kind words Dovias!
What a great video. After watching the video several times I've finally grasped the core concept.
Excellent, it made my understanding clear on Factory Method. Waiting for your next video on Abstract Factory Pattern.
Great content! Did you ever get around to creating the second video on the abstract factory pattern that you mentioned at the end of this video?
Super helpful. Thank you!
The coding part really helps! Thank you so much! Would appreciate a video on Abstract Factory.
Coming soon!
Nice video. Would be interested in seeing the composition version you mentioned. I feel composition is the way to go for most things in OOP
Great contact.. Waiting for the second part
Great clear explanation
Thanks a lot Daniel, your videos are great!
Thanks Ganesh! Glad you enjoy them :)
Very crisp, clear voice. Good teaching!
Would you make a video about why we need the factory pattern - what problems the factory pattern is addressing?
Hi Thuy, I see from your recent comment you figured out the value of this pattern! You hit the nail on the head :)
This is an awesome channel!
Thanks Aying! Really appreciate the kind words.
Great content thank you so much, I definitely subscribed,
I have a question, what if we have added the ItalianStore Class and we give the user the right the store in the main class how would you know which Store will be choose and how would you handle it since we don't wanna to expose instantiation to client
Thank you so much.
You're welcome Tahsin!
Good stuffs brother. Liked and Subscribed :)
Thank you and welcome to the channel!
What blackboard tool are you using? Nice clear explanation. Thank you.
Thanks!
Thank you so much!!!
Very helpful
Thanks!
Good. Liked. Subscribed.
Thank you and welcome to the channel!
quite an amazing course, I just want to say something that I wish it could be added which is how to approach using one of them "the use cases"
reply and close
Great clarification 👏.
Do we have a SOLID principles playlist ? I couldn't find it
Hi Naman! Not yet but this is a great suggestion!
did I miss the second part of Factory design pattern you have mentioned anywhere? could you please paste the link if you have posted on second part? thanks
I still didn't get it. Isn't the main problem described as "violating the Open/Close Principle"?
If we were to add a new kind of Pizza Type, we still would need to modify the if/else type block anyways, so how did creating all that new logic helped to solve the problem if it's still there anyways.
Great content though.
If the branching logic is still there in the second approach, doesn't it still violate the open close principle ?
In the last part, when you describe the NYPizzaStore, you break the Open / Close principle anyway, right? wouldn't it be better and optimal to split It in two other classes (NYPepperoniPizzaStore and NYCheesePizzaStore)? I hope you clarify my question. Congratulations on the great video!
Second this question. Wouldn't the NYPizzaStore still violates O/C principle if there is a NYStyleHamPizza added? Does having the factory abstract class do any better than the simple factory class?
could you please provide link for abstract factory deisgn pattern video as you have mentioned in video?
like your content, friend
Thank you very much!
Could you go over the Visitor Design Pattern?
Really very clear explanation.
Thanks Pooja!
Shouldn't all these methods be outside of the Pizza class pizza.prepare(), pizza.bake(), pizza.cut(), pizza.box(), createPizza() and instead maybe be in the Factory?
Good material, can not see git hub link for the code you used in the example.
Hi Muhammad, check out this link for the code repository: github.com/beabetterdevv/DesignPatterns/tree/master/patterns
I still have plans to create the remainder videos, stay tuned in the next few months.
Dude, this looks like a paid udemy course. Thank you for this!
but now runner needs to know the concrete implementation of the factory, which is again an anti pattern, should we create factory for getting these factory?
This channel is so underrated ...
Thanks Saed, I'm glad you think so :)
Is the Second part of this is ready?
I'm confused because there is thousands of variations of toppings on new york pizza, so is this method practical for this example? Wouldn't you have thousands of classes?
Why do you need the order method, since all it seems to do is call the create method?
Isn't it simple Inheritance?? Why are we calling it a pattern?
Midterm in 25 minutes boys. Time to set these videos to X2 speed
Hope you did well!
