Low Level Design 106 | Inheritance and Polymorphism | 2022 | System Design

[@rajaganji7982]

Love this LLD series. Thank you. Keep continueing.

Hello Yogita, Great content just wanted to know where is O principle? Am i missing the something in the series or was it intentionally not covered or will be covered in future?

[@architraghuvanshi8892]

Open/closed principle. The principle states that software entities like class, modules, functions, etc.; should be able to extend a class behavior without modifying it. This principle separates the existing code from modified mode to provide better stability, maintainability and minimizes the changes in the code. This is acheived using inheritance and polymorphism I guess hence this video. But I agree it should have been explained and mentioned in the video.

will never forget the bread example... excellent..keep going..

[@kamalkumarmukiri4267]

Hi Yogita, these sessions are very clear and it is really hard to make these videos with high quality. Thanks a lot for your sessions once again.

[@KunalLadhani]

Great series, thanks for providing LLD Content. Please keep making LLD series videos, one request - pls release more videos per week, placement coming up 😂

[@sudocode]

I totally understand. We are trying to be more consistent. You should see the results.

[@KunalLadhani]

@@sudocode sure, best of luck.

I have LLD round with Amazon on 13 May.. watching this helpful series on 1.5x 😇

How did it go Abhishek ?

[@mayankk104]

Great Content!, I have been waiting for the low level design course you promise, please come with it soon.

[@cronypau9970]

one of the best video on such an important topic!!!! kudos to you

[@piyush5701]

Hi Yogita, you said "polymorphism is an implementation of Inheritance", But I wouldn't say that, just for the example, we have operator overloading and method overloading, which are examples of polymorphism but have nothing to do anything with inheritance.

[@tekumalsaisaketh4509]

but how can we have method overriding without implementation of inheritance

[@rohitkumarsinha876]

Great content yogita

[@simply_homemaking]

Your content are great. Please share more videos about design pattern. Eagerly waiting for it

[@profitjourneywithsk2136]

very good and informative video series . Thanks Yogita !

[@elanza48]

Hi Ma'am, You explanations are great !

[@shahilyas5338]

Thanks for the great content. I am wondering if you have missed the open-closed principle or you will cover that later?

[@sumitbasu5146]

Thank you so much for all the efforts mam.

[@gazirizwan]

Good and simple explanation. 👍 Is it possible for you to deep dive into the concept of Interface, it's implementation and where it's really very useful in coding and how it solves the real world problems?

[@doctorstrange5477]

Please make a video on composition vs inheritance and when to use what

[@gokulsrinivasan8563]

Really great content!!!Thanks a lot

[@adityagarg9806]

Hi Yogita Can you please tell when we should use enum vs subclasses during lld. e.g like different spot in parking lot design

[@mohitthakur5904]

I was confused in same kind of thing, while I was giving a coding desgin interview, my approach was to go with the interface and classes for vehicles but interviewer said to use enums

[@26goutam]

Thanx for the video. Waiting for open_closed principle video

[@kshitijmathur1358]

You should rename it to express that you are mapping ood with solid. The content and presentation is awesome... Renaming may gather more views

[@kumar8134]

great content

[@jigar07cp620]

Mam, Polymorphism can be 2 types: Run time Polymorphism. compile time Polymorphism (method overloading). For run time polymorphism does it use vector table?

[@prathamsinghal5261]

Where is the video of the O in the SOLID ? Is it uploaded elsewhere ?

[@sayanroy9161]

Nice. But frequency of video is very less

[@saravanakumarradhakrishnan756]

Watching your video lessons at 3.30am that too Sunday midnight. These are the answers for burning questions i had in my mind for long time. I hate peoples describing polymorphism is different than inheritance i was arguing because I did not found any proof 🧾. Interfaces also meant for polymorphism, is that right?? Please answer

[@sudocode]

Both inheritance and polymorphism are different. Though they are related to each other. Its not a YES or NO answer. You should watch the whole LLD series once. And then, you will have a better feel of it.

[@tarushiarora8628]

is there video of open closed principle ?

[@Samiullah-vd6sm]

Have made it a piece of cake

[@postman12]

I guess this video should be about the open-close principle if we are following SOLID, thanks anyways

[@mashakpatel4962]

Ma'am what is ur salary and experience in UAE now in IT industry?

[@vasujhawar.6987]

I was hungry man, why did you took that example....

[@talib7508]

Polymorphism is method overriding?

[@lovedeepsingh5501]

And also method overloading.
