Thank you

Excellent 🎉
Comment from : CodingWithSankariya

Fantastic explanation extremely on point Thanks
Comment from : cspalfi

There is actually only one fundamental concept of OOP: MESSAGING brAbstraction, Encapsulation and Polymorphysm are direct consequences of messaging (inheritance is just a means to auto-copy code and not a fundamental concept, it is misused as one though)
Comment from : SnakeEngine

They say Algorithms and Data Structures are important for coding, which is not true; it is Object Oriented Programming Thanks for the video

Comment from : Omer Zafar

I have absolutely no idea what the difference is between abstraction and encapsulation I've watched a dozen of these and it's as if everyone wants to believe there's a distinction, yet they describe twelve different ways they're the exact same thing This is utterly bizarre
Comment from : Brandon Chapman

Amazingly succinct, clear and thorough!
Comment from : Iván Torres

😄 So, happy! In the first minute he defined an object as "anything you want to store and process data about" From relational database design I gathered, "that's what we'd call an entity" and the guy says "another name for an object is an entity" Ok! 💪😀

Most courses only tell you the theoretical aspects of OOP, but none of the practical ones Inheritance, in particular, is very problematic Why? Because the dependencies that exist at the beginning of a project may not be the dependencies that are turning out to be important as the work progresses and the software product takes its real shape Whenever that happens the carefully planned out inheritance structure of the project has to be broken up and redone This is much harder if an OOP style was used that basically casts dependencies in stone "re-factoring" is not a minor activity but it might become the major activity in such projects The better engineering strategy is to keep the code open to dependency changes by avoiding inheritance altogether

This is a new concept fo me and I've watched about a dozen of videos but should have started with this one The clarity and simplicity of the explanation are unmatched Thank you!

Will add to the pile of positive comments here and say this is the most concise, informative, and accessible video on the subject I've seen great work

I picked a book on OOP 25 odd years back TODAY i understood the fundamentals LOL LOL thanks for the video ♥♥

Comment from : Bradley R

this has been the best video i have ever seen - great analogies and loved how you included all the different terms used to describe the same thing - new sub
Comment from : theTertiaryAdjunct

This is a super clear way of defining and demonstrating the concepts ! infinite Thanks ❤‍🔥
Comment from : showaib haydar

I reckon many experienced developers who came across this video feel the cringe and flashbacks when they have been taught this great promise of OOP during their studies The really turned out to be so different Through my 20 years of software developer career I have never seen a software system modelled in OOP which I can say "yes! finally OOP done right here and that is why it is so easy to maintain or change" In reality the production systems I saw (those which used OO languages) were not using real OOP modelling of the problem they were solving And there is a reason for that In these simple examples it makes such an easy way for getting sold to a non-developers and managers They think that they can just model real problems like that and it will help you Wrong When you first time come across classes named like AbstractSomethingIrrelevantFactoryBuilder and get totally confused you will know what I am talking about And yes, "OOP experts" will say "oh, they just did OOP wrong" So, have a look at other programming paradigms, don't lock on OOP Take courses of functional programming, procedural programming, learn about data-centric approaches and data immutability It will give you perspective, and will help in your career

This is one of the best explanations that I have come across as a new learner it's very well explained
Comment from : UTR-Gaming

so clear, and easy to understand, thanks brgreat job
Comment from : Ong Wu

bNow/b I understand polymorphism Thank you!
Comment from : Justin Catterall

These examples use simple objects that are well understood as is their component parts Trying to objectify more complex ideas can be very difficult
Comment from : Igbon5

you are amazing brother !! thank God !!!🙌🙌
Comment from : Marina Nik

I learned OOP from a video that Philippe Kahn made about the subject when Borland’s Turbo Pascal first introduced this new way of programming It took awhile to understand and master the concepts, but after that, I absolutely loved it and it made large, complicated projects so much more manageable The ability to start with a base class and do inheritance was extremely powerful It literally enabled us to program our products in a fraction of the time and with fewer programmers than the old spaghetti code ways of coding
Comment from : Bill Kannen

Damn, this was awesome! Like…I know these concepts, but now…I somehow know them better
Comment from : Irwain Nornossa

Ewww Just let data be data and do stuff to them with functions
Comment from : beantown_billy

Hmm now terms encapsulation and API seem to be the same or at least very similar would you agree?brEncapsulation is usually used when we talk about OOP, and API is usually used more broadly - not explicitly connected with OOPbrYou also mentioned data hiding, another term that is usually mixed with encapsulationbrAll I'm saying is that there are very similar terms that are connected with each otherbrAnyway, beautiful video One of the greatest channels Thanks for creating this content for free!

Thanks for this I've learned it over my career but this is a great view I had the worst intro to this from a UCSD professor He wouldn't have made it in the real world

another fundamental concept not discussed often enough: "composition" - it models the relationship between two or more classes in such a way that a class can be said to "contain" (reference) other classes (as data, encapsulated or not), and represents a "has-a" relationship, as opposed to its antithesis, the "is-a" relationship (inheritance) example: a house has one or more rooms, and each of those have doorways, and may or may not have windows a cell consists of a membrane, mitochondria, nucleus and dna, etc

the best video about his subject!
Comment from : Lucas Vieira

The most important bit about inheritance is that if you ever think of doing it, don't It's literally never a good idea It's one of those ideas that seemed like it could work 40 years ago, and which has been well disproven for 30 years nowbrbrJust don't Future you will thank you
Comment from : Joni Hanski

Very clear presentation I feel there would be value in explaining why we want to bother with classes at all, rather than just using well-designed functionsbrbrClasses are valuable precisely to the degree that they help the programmer to manage both cognitive and programmatic complexity Calling a novel type of object into being can make code easier for humans to use, particularly when instances of that type represent something physical (like data, in the case of an ORM)brbrMany of the big ideas in OOP actually come from the philosophical field of ontology, which doesn't get nearly enough credit I recommend the "is-a relationship" Wikipedia page for anyone wanting to expand their diction and view of what's possible in OOP

Comment from : Venky Babu

Great breakdown/explanation of the OOP concept OOP is one of my favorite areas in computer science/programming applications Its not as an intimidating as it sounds Next: I would love to see a short video on the application of these four OOP constructs in terms of their application; write a simple program that demonstrates each of the four areas Thanks
