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 : )

[@aimendondo]

Dude, you’re making the lives of many future programmers here easy. Thank you for unlocking my computer programming skills and dreams come true.

[@luuchoo93]

I'm just starting with OOP and this has been the most helpful and straightforward explanation I've had so far. Thank you

[@JRJR-zb4wk]

The use of concepts to explain this is crystal clear. Wish lecturers taught just like you did in university. Appreciate it CS Dojo!

[@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.

[@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".

[@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.

[@Post-MoMitch]

Thank you so much CS Dojo! You're a great teacher and having another person explain this to me other than my professor helped me understand this concept a lot better. Keep it up!

Your way of explaining how Java works conceptually is the best I've ever come across. Thank you for this!

[@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.

[@baraj9695]

wow, I could not understand classes very well from other tutorials and this is the first one that helped me as a complete beginner in programming. Very patient, gradient and logical explanation, thanks.

[@ohtexankorean5567]

Wow! Thank you so much! I'm taking an online Java course and this by far is the best tutorial on OOP. Very good production quality and teaching techniques.

[@jonathaningersoll6213]

Excellent. Thank you. It's taken me year to understand this and you made it very understandable!

[@reddzltuano8176]

This video just made my life so much easier. I feel like I can learn anything now. My online classes are horrible

[@yesandno2217]

This is incredibly simple and effective demonstration. Stumbling upon and reading upon these concepts without proper visual example is quite tough for beginner. You've taught me more in 20 minutes than I did on my own for a past week upon these concepts. Thanks so much.

[@luishnavarrete]

Thank you so much for this good explanation, especially code written in java, I really appreciate it! Go on with this useful videos.

[@buhnanner2935]

I am so glad I started watching this series. My main coding goal at the moment is learning python and I just wasn't familiar as I had wished I was with the theory behind Data Structures and such. Even though the examples are in java, to have such a clear explanation behind why OOP should be utilized I feel will have a huge effect on my coding efficiency

[@jasonpyle4302]

Been struggling with this concept taught by another online course for a week now. The way you explained it made so much sense. Thank you!

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.

[@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

[@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. :)
