Just go through the libraries and the namespaces used in linux code. Thats the best way to understand OOPs. When C++ compiler can covert that c code and layout into OOPs only then we can totally understand how OOPs is being handled.
For me encapsulation is not only about storing properties together and decreasing number of arguments, but what is more important it is all about HIDING implementation details and PROTECTING code from random access. At the same time abstraction is about ignoring unimportant parts of objects providing only essential interface for 'outer world'.
Computer scientists: "ah yes this is an implementation of polymorphism and encapsulation" Also Computer Scientists: "This some spaghetti code right here"
as a CS major who is in my Senior year.. this is a great clean & concise explanation on the basics of OOP...I came to this video for a refresher since this is material we went over my first year ....I rarely use OOP but i definitely should ..would of made my life at Uni so much easier
I just looked at so many different explanations of OOP for my interview prep including the "simple for even a child" freecodecamp explanation but this one is by far the best one! Great work. Thanks :)
The harsh reality is, though, that you probably don't understand from watching this video to pass an OOP exam. It takes years to get to a professional level of understanding of OOP. It's a major dedication, as opposed to something that can abstracted and encapsulated into a short video. And that's not even telling you that this video contains errors, despite the speaker's voice being very confident.
Nice work. I have no doubt that you are a competent programmer, but more importantly as a teacher, you are a gifted presenter. I usually have to watch tutorials at 1.75 - 2.0 times normal playback to keep from stabbing my eyes out. Your tutorials are actually enjoyable at normal playback speed. Thank you.
Encapsulation is just not about making variables private, it is much more. It is about breaking up the application into different logical and organized parts. So that you can change one part without generally changing all the other parts. Therefore encapsulate the parts that vary from the parts that remain the same.
With Encapsulation: Resides Object oriented programming backbone of encapsulating data and functions into single unit called object With Abstraction: We reduce the impact of change in other objects With Inheritance: We can eliminate redundant code With polymorphism: We can refactor codes according to different types in simple manner
You got the definition of Abstraction wrong, and your definition of Polymorphism is not quite right. You wouldn't be refactoring anything to achieve poly.
@@kcs3248 But that's not really what polymorphism is. You don't have to refactor anything, and who knows what in the world he meant by "according to different types". Types of what? One of his other definitions was also not right. Just be careful what you read if you are trying to learn OOP. There's a lot of impressive-looking videos about OOP and many of them are wrong.
Great video! I am trying to teach myself C# and I really struggle to research certain things when I get stuck because I don't know the name of the concept that I need to look into. This video lays a lot of the groundwork in simple and concise terms. Thank you!!!

Been programming for 22 years and going to try OOP for the first time. Looks like it will make my programming easier in some aspects. All this time I got away with procedural programming and my current job (programming automation) does not need me knowing OOP but I hope to get a job in software engineering, and I feel OOP is a must to master.
Woah that DVD player metaphor is outstanding. I’ve been really struggling with wrapping my head around OOP but that metaphor really helped things click for me. Well done, and subscribed! Looking forward to checking out your python vids!
This was so needed. There's tons of material out there explaining OOP. But usually the explanation is either vague or a bit impractical. Congratulations for not beating about the Bush and yet not missing anything important.
This is the first ever video that I watch about OOP, in fact this is the first ever information I learn about the OOP. Honestly speaking - I grasped the general idea. After watching it two more times I think I understood the concepts. From a single video from the first time. Thank you, Mosh!

@@One.Zero.One101 I didn't miss the point of what the guy was saying: "College text books are too hard". OOP takes years to get good at, assuming one's brain is worthy of the challenge and the commitment. And yes, I'm tired of people lying on their resume claiming to be good at OOP, when in reality they were just intrigued by a fancy TH-cam video and have just dabbled in writing classes . I saw one misuse of the word "interface", and then jumped a little past half way and found another mistake @ 4:39 (confusing abstraction with encapsulation). So as pleasing as it may appear to a newbie, they easily could walk away misinformed. It's easy to be attracted to easy material, indeed, but it's also easy to be misinformed and not realize it. That's my complaint about the majority of people who quickly fall in love with an educational video, not realizing the information is not quite right. I think people should read OOP books written by authors with well-established expertise, and not be so attracted to fancy youtube vids.
Mr. Mosh, thank you for explaining Python in such a base-level common sense manner. You took a 4 hour class and summed it up better than the CISCO Network Academy that I'm going thru. Thank you so much!
I don't even know why I'm watching OOP-oriented videos - I was simply searching for UE4 Blueprints tutorials, so only loosely related topic - but that was a very solid explanation. Thank you, I'm glad I've watched it.
To be honest, I like every tutorial of you on programming. In PNG the university dont have such a lecturer that can explain in the lectures room the way you explain in all your upload tutorial its amazing.
Thanks, Mosh! I learned a lot! I just learned to code recently, but I am really passionate about it. I hope I can always be a better programmer over time.
"We can change or modify one of the methods and it will not impact the rest of the code" - famous last words ;) Class extending, sharing "this" all around the place, mutating the state - that's all the consequences of OOP and it WILL impact the whole program. Granted - it's all about the patterns. But we all know how you can end up with "Spaghetti" code even with OOP. Not to mention presented "Procedural" programming claims should be also contrasted with Functional Programming since Procedural would focus highly on imperatives rather than abstraction functions. Beginners could easily confuse Procedural with Functional at this point. With that being said - thanks for gr8 video :)
As a person who has bought the complete Mosh courses i must say that the paid content is EVEN MUCH better and i highly recommend anyone to purchase his courses. This is not a sponsored post, i have not received a damn $ from Mosh but i truly wish i had found his courses when i was learning .NET development at first!
Let me guess, you are just another fucker from India who is so confident but really doesn't understand any of this shit but are more than happy to lie on your resume and act like a confident fucker.
But in reality, you couldn't watch this video and pass a test over OOP. Not to mention the mistakes in the video, where he uses the wrong word, like "abstraction", which has nothing to do with reducing impact of change. So in reality, just because this video made you feel good, you have a long road ahead of you to become an expert at OOP.
C++ gives you all of those benefits, plus procedural when need along with lambdas, functions pointers, function objects and templates consisting of function templates, class templates, and variadic templates... but c++ also gives you the added benefit when a set of classes that are related can reference or modify internal protected or private members by labeling them as a friend. This doesn't account for the fact that C++ is a strongly typed language, and has various storage type classifiers such as static, const, mutable, inline, etc... Modern C++ also has constexpr which is a very useful precompile feature. Suppose you have a class called Motor this could be a nested class within a Car class, however, you might want the Motor class to be an independent class because you can have a motor in a Boat, a Bike, Train, Plane, ATV, or it can even be an electrical motor to some kind of power tool. So in this situation, your base Motor class would be complete abstract, then your VehicleMotor class would derive from that. Then your derived Vehicle class objects such as a Car would have friend access to the VehicleMotor class so that it can change its internal properties such as HorsePower, NumberOfCylinders, etc. Now the Vehicle Motor class might not be able to access the Car's private members directly but could be a friend to access its private methods or its protected members... This doesn't even account for the preprocessor directives and macros. Yes, many people frown upon Macros, but in some contexts and if done carefully and correctly, they can make for good text expansion and replacement. I wouldn't rely on them for setting or changing values, or passing data types around, but they can still be useful. With the current release of C++20 in which I do not have a current compiler as of yet, we are now being introduced to Concepts, Coroutines, Modules and more! It's just that with C++ you need to know what you are doing as C++ will allow you to write code to shoot yourself in the foot as long as it compiles and links and provided you don't have any run time errors or crashes. You can still have memory leaks, dangling pointers or references, invalid pointers, and references, etc. Other things such as out of bounds indexing or accessing memory that doesn't belong to you will cause unhandled exceptions. Knowing when to cache something into a local variable within its a specific scope or stack frame is vital compared to knowing when to put something on the heap. Dynamic programming is good in many contexts but one has to be careful, that's why the standard library is so versatile with its containers and algorithms, smart pointers, etc. C++ gives you almost all of the concepts of OOP without the garbage collection of C# and Java with very minimal overhead and more. It is also considered a lower layer of the high-level languages next to C and Objective C, any lower and you'd be working with ASM. It is very fast and efficient and when done correctly, the source code for the application or the program is practically invisible as modern C++ compilers are excellent at what they do and are only improving. They aren't completely perfect as they do have bugs, but they can generate object code or assembly code much better than you can! They will utilize specific operating system functionality and CPU instructions in manners that you would never think of! Their error messaging systems are becoming much better along with their linker and debugger tools. I've messed around with C# a little, JavaScript a little and Python but when it comes to the type of programming that I'm into doing such as 3D Graphics Rendering Engines, Hardware Emulators, Sound Processing, Compiler Design, etc. this is where languages such as C, Objective C, and C++ excel above your high-end languages. If you're looking to do something quick and fast such as an online interactive program for quick access and basic functionality then yes, by all means, Java, JavaScript, C#, Python and others are perfect for the job. However, when you are writing the backend, frameworks, libraries, server code, etc. that's where these languages are usually preferred. This is why C++ is considered a multi-paradigm language! It can still work like C, it has the ability to inline assembly blocks as their own scope within a function for optimizing loops, etc. the capabilities such as C# and Java without the overkill of the garbage collection, and it isn't restricted to have everything as a class or an object or a smart pointer behind the scenes such as seen in Python, C#, or Java. However, it is a strongly typed language which makes it a great tool to master! Happy Coding!
@@muhammadshoaibmushtaq5693 No, not at all, just pointing out some of the benefits of the language. Don't get me wrong, there are also cons, but the pros outweigh the cons by a huge advantage!
@@ChrisFouadHabibifromMars This may be old but I'll appreciate your reply to a question if you don't mind. Do they ask questions concerning these in interviews?
Funny how things change, In the era of modern application development, where components and microservices dominate, procedural-style short and modular code might seem more appealing these days. It provides a practical alternative to the complexity of OOP, helping you build fast, maintainable, and scalable small modular components with less overhead. Sometimes, less really is more.
Thank you Mosh, I really enjoyed this concise and clear video. I understand what OOP is now and can’t wait to get to that topic in my learning. I have just started learning to code in Python.
Encapsulation : in oop, we group related variables and functions that operate on them into objects Abstraction : all that complexity is hidden from user
This was very good, I read 5 different explanations of OOP before coming here, I had the basic idea about the terms but it's definitely clearer now, what each term actually means.
I code pretty well with classes on C# and I know access modifiers and class responsibilities and make clean code, but I still don't understand OOP concepts. This video helped me understand it.
Thank you for the super clear and short explanation, it has helped so much, could you explain the difference between functional and procedural programming in a similar video ?
"The best functions are those with no parameters" No ! Please *don't* interpret this as "Functions without parameters are better !" because it's *not true* . Just because someone famous said it doesn't mean it makes sense.
@@rumfordc it's more meant that instead of building some very complicated structures to avoid functions with parameters, just use one functions with a few parameters (for example I once saw code where someone built a whole object with 10 methods resulting in about 200 lines of code instead of just using that one function with 4 parameters directly)

@@skilz8098 lol, I was just kidding. Thanks for sharing.
You just wrote a book dude haha
@@Azul719 It's barely a chapter. Only a few paragraphs.
I love your videos! There always so easy to follow and understand. This one definitely didn't disappoint!
Well done. Thanks for sharing this content. Simple and easy to follow.
Every computer science lecturer should watch and understand this video before confusing the students. Thanks Mosh Bro.
Let me guess, you're just another fuck head from India?
@@HOWYOUDOIN884 oh u mean ur future bosses? 😂
I'm already applied these concepts in my code without even knowing the terms for that. At least now I know
Your sketch showing object property as variables and methods as functions really sparked a light in my brain. Thanks.
Mind Opening, Informative, pactical
Other courses make it so much more complicated to explain what here has been plainly expressed. Congrats!
What a brilliant Video! Thank you!
That's the best video I've ever seen about OOP. Here I found lot of info I coudn't find at other sources! Thank you so much!
Great video I wish I watched this before my interview. You forget these things
Yeah man same, like i understand it in my head but I get nervous
@@ChrisFouadHabibifromMars This may be old but I'll appreciate your reply to a question if you don't mind. Do they ask questions concerning these in interviews?
Funny how things change, In the era of modern application development, where components and microservices dominate, procedural-style short and modular code might seem more appealing these days. It provides a practical alternative to the complexity of OOP, helping you build fast, maintainable, and scalable small modular components with less overhead. Sometimes, less really is more.
Thank you Mosh, I really enjoyed this concise and clear video. I understand what OOP is now and can’t wait to get to that topic in my learning. I have just started learning to code in Python.
Encapsulation : in oop, we group related variables and functions that operate on them into objects
Abstraction : all that complexity is hidden from user
Came with low expectations, but it was actually really good, tnx
Best description among many and many text books and papers that I have read or videos I have watched. Thank you Mosh!
That was a lot of info to cram into 7 min. Bravo!!!!
Danke!
One of the best explanations about the subject. Well structured and easy to follow.
I can say nothing but. Thank you for sharing your knowledge with those that want to learn programming.
flawlessly explained. Thank you, Mosh.
This was very good, I read 5 different explanations of OOP before coming here, I had the basic idea about the terms but it's definitely clearer now, what each term actually means.
This is only of the best one can find! Thank you so much. :)
I am trying to learn some programming and your video presentation is wonderful!
Thank you !
your way of teaching .....awsome man..very well explanation..!!
I code pretty well with classes on C# and I know access modifiers and class responsibilities and make clean code, but I still don't understand OOP concepts. This video helped me understand it.
Your videos are simple to understand, you make very clearly for .net platform... Thank you for your videos👌😔🙏
Programming with Mosh definitely bcoz you are the only TH-camr who makes super quality videos on dot net...
Let me guess, you are a fucker from India that just likes to agree but doesn't understand shit, and you also don't wear deodarant?
Sir, you are an excellent teacher.
That was so beautiful. I love you.
This is the best OOP explanation i've ever seen. Thank you so much for that!
Started good explaining encapsulation very well but after that, he just tried to finish in 7 minutes.
I disagree
Clear, complete and straight to the point, thanks!
@Sergio Díaz Nila Didn't know that, thanks for the tip Sergio!
i liked this video so much, it's really informative and perfect explaining
Yeah, Mosh is great at explaining things
Thank you for the super clear and short explanation, it has helped so much, could you explain the difference between functional and procedural programming in a similar video ?
Personally, I think switch statements are beautiful.
You’re an excellent instructor. Thank you.
nice explanation sir, thank you 👍👍👍🙂🙂🙂
Sir aap bhi bahut acha explain krte h
As somebody relearning how to code Java, Mosh's youtube releases have been invaluable.
Thank you so much. It took me years to understand what object-Oriented programming is and this video explains it so well.
Except for the mistakes and wrong definitions ;)
Very clear and you make the subject interesting! :)
simple analogy comes from the person who understand it.. and you made oop become clear.. thank you..
done, without any doubt.. :)
I felt personally attacked in that intro, I have a variety of fettucine, cavipati, angelhair, bowtie and penne code thank you very much.. :D
Thank's profesor, your my "STAR"
"The best functions are those with no parameters"
No ! Please *don't* interpret this as "Functions without parameters are better !" because it's *not true* . Just because someone famous said it doesn't mean it makes sense.
True. One should read the mentioned book chapter before making a video with that bold statement without the full context.
do you have any examples of when you would prefer _more_ parameters when _less_ is an option?
@@rumfordc it's more meant that instead of building some very complicated structures to avoid functions with parameters, just use one functions with a few parameters (for example I once saw code where someone built a whole object with 10 methods resulting in about 200 lines of code instead of just using that one function with 4 parameters directly)
5 years and still a very good explanation. Bravo!
