Except the regular Design Patterns which we use daily in our work like Singleton, Factory, Facade, Proxy etc. which makes sense as we anyways use them daily the other patterns used to feel boring and uninteresting to me as even after reading from books and tutorials the concept just remained as theory. I felt they are not as important as we don't use them much. For the same reason i was also going to make them less priority from your playlist as well. But thanks a lot to your amazing practical explanation i am finding each Design pattern so much practical, interesting and useful and easy to remember and apply.

well done

I was asked similar question in Amazon. If I have watched this video earlier, result would have been different. Thank you Shrayansh for uploading it.

Nice explanation ! This reminded me of your isA hasA both properties needed in the Decorator pattern. This also looks similar but isA(Expression) hasTwo(Expressions) + Internal Operation. Thanks!

Great explanation! Really appreciate your work. How can we create mkdir method in filesystem using this approach? Mkdir should be a part of only directory and not file and that need be be recursively call using ((Directory) file).mkdir(), is there a way to avoid this and use same design pattern?

Thank You

How would I handle multiple files in a single folder situation? Would we: 1. Create the first file as a leaf and then all subsequent files as file systems with only leaf and no child file system 2. Modify the filesystem object to have an array of leaves and an array of child file systems Please let me know which one would be the better approach? PS: Honestly, great work. I come from a place where I do not have much hands-on coding experience and these videos have really helped me and challenged me in the right kind of ways that I now feel much more confident with LLD. Great work man! Hats off to you!!

List implies that Directory can have either have a list of directories as leaves or list of files (leaves of files). The iterator in the ls() method will iterate over each file and call its ls() to print filename.

Sir @Shreyansh there is one doubt that I have regarding the file system, I don't know whether I have misunderstood the problem itself, suppose I have directory ABC and in ABC I have like three other directories-> BCD, CDE, and EFG in BCD-> I have GHI, in GHI-> I have FGH. so according to your design it will print like in preorder dfs wise all the names(ABC ->BCD->GHI->FGH->CDE->EFG), but in practically if i pass ABC.ls( ) then it should print only (BCD,CDE,EFG) so how can composite design pattern help here?

actually here it is designed in such a way, that it print whole structure i.e. all nested files/directory

Hey Shrayansh, if we were to add a new operation, say modulus, then we would need to update the existing Evaluate()'s switch case to accommodate it. Thus, violating 'O' of the SOLID principles. How should we handle that? Is it by having separate class for each operation with its own evaluate method implementation?

@prakharjalan7546

Maybe we can define a method in the enum itself?
