I am back with Design Pattern Tutorial video! BUT this is the pattern that I personally used to find most confusing!
I have tried to break it down into very simple conversation, a LOT of effort has gone behind this one video but I hope it will help clear concepts.
Let me know your feedback, it helps me improve and create better content.
Please continue your love and support for tutorials, it will motivate content creators to teach more!

you can improve it a bit by returning the instance in each build function. this way it's possible to chain calls: desktopBuilder->buildX->buildY->buildZ->getDesktop()

@adityatripathi1904 Жыл бұрын

Actually thats an essential part of builder pattern in functional programming. That way we can create a “chain” for object generation through deserialisation.

@anubhavanand2432 Жыл бұрын

I have one question, why do we need builder if we have setters for all attributes in java class?

@niwanshumaheshwari4534 Жыл бұрын

@@anubhavanand2432I suppose without a builder pattern we have to call Object.setProperty1() Object.setProperty2() But with a builder pattern we can do that in chaining, like one after the other. I think it's more readable like this, not sure if I'm right though.

@suchismitagoswami5609 2 ай бұрын

Great Video. One improvement we can make here is to encourage immutability by avoiding setters on the actual object. The intent is to allow an object to be modified during its creation phase, but avoid modifying it once created!

Inplace of just directly explain what is builder class u can explain what would be the problem we face if we don't use it. Then it ll give better understanding of it. Over all it is a good video 👍

Doesn't this pattern have a similar problem for which we used the factory pattern? For every new type of desktop we have to create new files and separate methods for building components. Do people actually use this? I feel it must be used in combination with the factory design pattern to handle the creation of different parts.

help me out for this question. Assume you are developing an API for a blogging platform using Node.js, Nestjs and GraphQL. The API has features like creating a new blog post, fetching all posts by a user, fetching single post details etc. One of the challenging requirements is to implement full text search functionality on blog posts i.e.. users should be able to search for specific keywords in the entire content of all blog posts. Given that MongoDB is your primary database, provide a detailed solution on how would you implement this requirement. Your answer should include steps from indexing data in MongoDB for text-based search to querying it using GraphQL.

Why can we not create 2 derived class directly from desktop (HP and Dell)? That would allow us to customise the building process. What is the rationale behind creating a builder class separately?

@gauravbagul7580 2 жыл бұрын

While building the object, can we have the DB calls to save the object parts into multiple tables? Because if we write the DB insertion code in the main code where director gives the final object, we may have to iterate object again

I've been doing coding for 30 years, and can't understand the use of design patterns. I am lone developer. Only a few times I had to put pen to paper to help visual then code complex ideas, but I mostly start coding after hearing a concept.

Thanks for doing this in C++ . I am crawling the internet for LLD course with C++ so that I can prepare for system design round . Do you know any learning path for system design High level ( I have bought grokking the system design interview from educative.io ) and for low level design. Your videos are surely helping a lot 🌼🌱💚

While I understood the design pattern , I am having a bit of hard time in grasping where this should be used , as we could have used multiple constructors , and also even while using this pattern if the individual parts like cpu, monitor etc requires any arguments that anyway we'll need to pass , only thing is that the order of the arguments might not matter.

The main function should look like this. If you don't want to delete, just create your objects on stack like, LenovoDesktopBuilder objLenovoDesktopBuilder; then call DesktopDirector Director1(&objLenovoDesktopBuilder). int main() { HpDesktopBuilder* pHpDesktopBuilder = new HpDesktopBuilder; DesktopDirector* pDirector1 = new DesktopDirector(pHpDesktopBuilder); Desktop* pDesktop1 = pDirector1->BuildDesktop(); pDesktop1->showSpecs(); delete pHpDesktopBuilder; delete pDirector1; DellDesktopBuilder* pDellDesktopBuilder = new DellDesktopBuilder; DesktopDirector* pDirector2 = new DesktopDirector(pDellDesktopBuilder); Desktop* pDesktop2 = pDirector2->BuildDesktop(); pDesktop2->showSpecs(); delete pDellDesktopBuilder; delete pDirector2; return 0; }
