Let's dive deeper into Object Oriented Programming with our Person/Pet example. We currently have a Person class and a Pet Class. Scott and David build the blueprints to expand our Pet example with base classes, abstract classes, and derived classes.

This is literally the best instructional video series on programming I have ever encountered. Please, for the love of all that is holy, keep making these videos!

@nxxd 21 день назад

I would like to echo this exact sentiment. David and Scott, you're both great and I really hope to see more videos of you together!

@MrMitri22 8 месяцев назад

Thanks for the positive energy! Had a great time with you mates. Personally, I find your pedagogical approach to be highly effective. I greatly appreciated the balance between the little jokes, the beginner-friendly mindset, and the valuable practical advice. I'm impatient to see you in the next C# modul!

among most of the tutorial series in the channel , you guys were the best. thanks for the videos.

@jamesp1389 7 месяцев назад

This was great. You both have a gift for breaking things down. Objects and constructors finally make sense to me!

02:15 I know this is rehearsed but the "oh crap" was heartfelt!! :) an acting profession awaits when AI takes over programming!! :)

@himanshu.g345 21 день назад

Thank you, Scott and David. You have cleared up a basic concept related to abstraction that I struggled with in college.

@marct8263 8 месяцев назад

Coming from a functional language this has really helped me get my head around OOP and how its implemented in c#

@dinindukanchana8554 4 месяца назад

What would be the NEXT best playlist to watch after finishing "C# for Beginners"? I definitely learned a lot from those two awesome instructors.

@Dariansweb 15 дней назад

I am not certain where to go from here. I'd like to continue learning more in deptch about each of the concepts taught n this videos. I am reading all the documentation on the MS Learn but would like additional videos that supplement these in the Playlist. Any suggestions? I don't want to go off into different areas before I get more stable here, like... don't send me to Blazor or Entity Framework, etc.

@kodindoyannick5328 4 месяца назад

Thank so much.

Amazing

@mr_don_key 4 месяца назад

I think it would be more useful (in terms of learning), to use a concrete (real life) business case to solve. E.g. a real usable to-do list, or a notepad, or a calculator or whichever suitable application. All this from A to Z (X-Y-Z being an advanced, with modern writing/refactoring videos). Also show what happens when not using good/best practices. E.g. show the exploit, show what happends in the real application. by doing this, i think people will understand the language better, and concepts behind it too. Instead of vague, non realistic, abstract use cases.

@bernpaul9868 Месяц назад

Sir please add more c# tutorial

@ronphil6666 Месяц назад

Great series thanks, but this last one was tough for me, to be honest

@senuhy 23 дня назад

What was the tough part in it? maybe I can help

@krishnareddyyerram4615 20 дней назад

Super

@bilalbyte 6 месяцев назад

Please upload some more videos on advanced topics

@donireland6218 6 месяцев назад

Very cool explanation. Using your example, how would you deal with pets that don't make noise (lizards, corn snakes etc)? Would those types of pets not have a MakeNoise method? Or would you use some other way of dealing with the question?

@Nobiotera 4 месяца назад

I saw your comment and tried to find an answer. I made it work by putting it like this : public override string MakeNoise() => null; I'm kinda late but hope it may help

@fyu5991 6 месяцев назад

since we can't create a Pet instance why is the constructor (string firstname) for?

@atulkrjha 4 месяца назад

According to the inheritance principle. First base class constructor will be called and it will initialize the firstname property to the name passed.

It's "Beyoncé"!

@ShreyanshiTimes 21 день назад

Now the list initilizers are too impressive, all you need to place is [] instead of new();

@nwngenisys8969 6 месяцев назад

This is too abstract for me... :P

@kking999 5 месяцев назад

what is next ? which lesson we can take further ?

@kking999 5 месяцев назад

the lesson was difficult for me , I don't undertand why they made Pet list in the person class, they should made the dog list or can in person class ?

@gower1973 5 месяцев назад

If you just created a list of dogs you could only ever add dogs, by creating a list of the base class you can create an object of any derived class in this case Cats or Dogs you cant create an instance called Pet because its abstract

@ellisrichards3381 3 месяца назад

I hope that helps this vid make sense. The List is a generic Type collection. Meaning if you made a list of Dog then only Dogs could go in the list. But since they made cat and dog derived from the pet class, dogs and cats can both be placed in the same generic list of pets. It’s the beauty of inheritance in OOP.
