Finally! this is the exact kind of definition I was looking for, literally has watched many video of oop but still was confused what exactly is object but now finally my doubts are cleared and i am satisfied, so thank you very much, you are the best

[@kools67]

How are you progressing with your coding, OG?..I have just started on Python and I am loving it...I too got confused with classes, and objects and methods, this video nailed it for me : )

[@czarekdupa]

Hey, thank you so much. I had such a hard time understanding what a class and an object was. This video was simple and easy to follow and I appreciate that. If anyone is still having trouble understanding the difference, I see a Class as a noun, for example, "a city". An Object. On the other hand, is a proper noun such as "New York city".

I am re- learning fundamentals of computer science, after decades of my first introduction. From my experience the definitions and alternate naming conventions are troublesome areas for me as well as others I guess. If possible you could provide better understanding in this regard. This could result in a better quality of understanding of the area of study.

[@ptsdarren6223]

Really enjoyed this. Sometimes classes, algorithms and data structures can be a little hard to wrap my head around. You are a great teacher and helped me understand this better. Thank you.

🎉Best explanation ever❤ I have been watching nine courses teaching class and object. None did such a great job as you did here. They don’t or can’t really explain the complex concepts. Your visualized explanation is so easy to follow that the thick fog is clearing up and now I can see the whole world of pthon. Thank you, 🙏 Could you do this (the coding part) in Python?😊 also, you shoul write a book “Python “visualized”

[@opeyemijonah8530]

The constructor explanation is gold!

[@putonghua73]

Agreed. I'm a perennial toe-dipper, who in the last few years has decided to dive into understanding Comp Sci fundamentals via CS50X and predominantly C. This was a very clear explanation of OOP basics that I can weave into my existing knowledge framework. The constrictor explanation made sense because of the time taken to build up from basics, before demonstrating DRY principles via constructors.

[@anuvaagarwal3492]

Really great explanation! Thanks. Will look for the python version as well

You're the best. You've helped me a lot ...I was worried if I could do well in my exams ..but your videos helped me a lot and I scored an A in my exams ...keep it up and post regularly please

What a good explanation for a relatively abstract topic. I had read about it but it still didn't make sense. You made it clear and easy to understand. THANKS... :)

[@jillianlee950]

This is the first time I’ve been able to understand the connection between objects, classes, constructors, and the “this” keyword, and Java isn’t even a language I’m familiar with. Thank you so much! Your teaching style and visual aides are very well executed.

[@cano4458]

I'm confused, isn't tom heavier than Jerry? I mean Jerry is a mouse. Dislike! Just kiddin

[@johnverbendoy]

hi, i watch a lot of programming for beginners video, because i am more better to understand codes in watching videos rather than reading from books, what can i say is you are really good in explaining the basics of object oriented programming compared to other tutorial. I hope that you will not be tired on making programming videos. thanks a alot. Godbless

[@stef6963]

the reason people learn more from this video than from their lecture/class, is because he did not do it Live. Your teacher skims through something, then expects you to ask questions(which most people are too shy to do unlike the 1900's). It would be harder to ask the content creator because he has thousands(maybe millions) of students. So, content creators fit every question that people might ask into a video, to teach a mass population. Hopefully this explained modern days for you guys, peace.

[@aaronjohnson2215]

Really good. What I often see is Person person = new Person(); For rookies its unclear why person is there 3 times. At least now I know that Person in variable type, person is a name and Person() a class reference. My question is: can type Person be ever different to reference Person()?

[@muhammadusman7217]

Well basically to become an app developer there are 2 category 1. IOS (you need a MacBook, and you should know the Object-C) 2. Andriod (You need to learn Java and learn the OOP concepts of Java, it will help you a lot and sites docs.oracle.com/javase/tutorial (I've learned a lot of Java from here) www.javatpoint.com (Just take the concepts) and if you have like any problem like in the code or stuff like that visit Google and StackOverflow, and MOST IMPORTANT You need "Andriod Studio" for making the android apps. :)
