Interface vs abstract class in Java C#

Interface vs abstract class. What is the difference between an abstract class and an interface? When to use an interface? When to use an abstract class? java interface. Are interfaces better than abstract classes? Is an abstract class better than an interface?

collection of common properties -> abstract class
common methods to be implemented in different ways for different characters -> interface

Oh god, this was so condensed, so short, so straight to the point, so well explained. No BS, only OOP. Thank you very much, I want to hug you Prof. Sluiter, but I'll keep it to a subscribe and a like.

Very helpful, thanks. You seem quite annoyed by the fact the princess does jack hsit besides screaming,

You've earned a subscriber. Keep up the content. I'm very happy with the length of the videos. It makes the concepts very digestible and allows me to think about it a bit on my own.

I finally understand it. Thanks for the simple, easy to understand example.

[theaskew]

This is quite possibly the best explanation I've ever heard. Thank you so much!

[jadenguyen]

This video deserves much more views and should even be shared in many programming lectures !
Thanks so much for the good explanation !

[Michael-loht]

Perfect explanation. I especially love the example visually to show them side by side. Most other videos seem to use self-referencing descriptions or other OOP definitions. But this is plain and straightforward. So at least now I know how to use them. Great for initial setup blueprint for how the rest of the software should be designed. Thanks

Brilliant explanation, thank you. It's really apparent that you are a professional educator.

Best “real example” about abstract and interface I ever seen!!

[andrewcenteno]

. I've been struggling with this concept. This was so simple, thank you

[romaneaugustin]

That's a good professor. Thanks prof Sluiter.

[MalcolmTheRealtor]

Thank you so much I had trouble retaining the whole concept until you just broke everything down

[jaredlising-simplybrewedph]

Damn, I was struggling on these two and you have made it crystal clear with my childhood video game:) thank you so much!

[diegolcdtm]

You explained it perfectly with a good example and the video is not too long. You got a new subscriber

[saadidriss]

amazing explanation! too often are these types of tutorials dependent on an overwhelming amount of unnecessary vocab words instead of simplifying the topic at hand to generate a better understanding. Thank you sir.

Donkey Kong was a great example and was relatable, thank you!
