Hi, pls create a video to explain for Covariant and contravariant
ОтветитьNothing related to coding, but I like the fact you didn't unwrinkle your t-shirt and don't care about the late afternoon sun removing half of your facial expressions at the beginning of your video.
ОтветитьAbstract Base > Inherit > Implement abstracted target interface... avoids issues with dual inheritance. why not just use virtuals?
ОтветитьThanks for the explanation. I think your voice tone and speaking rhythm could use a bit variety. I lost my attention while watching several times.
Ответитьgood video, tho i would suggest going/running the code to exarcebate the difference between any 2 approaches. You did show the code, but it's hard to grasp between the 2 without running them
Ответитьthe legend is back
ОтветитьGiven that this would be a great topic for newer developers to understand better, I think the video would benefit from slowing down a little bit (or reducing the scope, if you want to keep it sub 15 minutes). Don't get me wrong, you are saying a lot of really important thing, but even with 5 years of .NET experience, I had a hard time keeping up on everything.
ОтветитьI think in C++, you can have multiple inheritance just not Java and C# using abstract classes.
ОтветитьI noticed I could use public, internal, and protected access modifiers in the interface. I couldn't use private though
Update: doesn't work when inherited from another project. Insisted on public modifiers but worked when implemented 'explicitly' for protected modifiers regardless
Great video! I have two more points which were not mentioned (I think? Or maybe I also forgot haha) - A class can implement multiple interfaces, but only one abstract class. Also maybe the fact that default interface implementation methods can't act on any dependencies coming from the implementing class, it's essentially a static context.
ОтветитьSir, please explain bit slow. Content not able to reaching.
ОтветитьI like your wall its intresting
ОтветитьWhat's the editor?
Ответить🎉 nice seeing your FACE in my notifications
ОтветитьIdea for content: openiddict-core
Ответитьwhat's your ide and what theme were you using in this video?
Ответитьwelcome back
Ответитьone thing is, if you wanna change the interface like adding new method / property to it, it will break all implementations. And if you make new interface to replace it, you need to document it and educate other devs in the team. It's disaster especially for package / framework devs. So one important rule would be: If you are going to design an interface, design it very carefully and target it to the future.
ОтветитьThanks for this video, very informative. Just a couple of questions about Abstract Classes compared to Interfaces. You mentioned that an abstract class is when you have a set of things that have a commonality and then you take that commonality and abstract it into an abstract class. Whereas with interfaces you said you want to separate the thing that a component is dependent on or the things that its consuming and this is where the bridge or contract comes in ultimately used to decouple your components into code. That went straight over my head lol. What I think I have discovered and why some people struggle with getting a sound understanding of the concepts is that maybe its because there is a coding benefit in using abstract classes and interfaces as well as practical advantage.
ОтветитьHey there! You are missing a "t" on your thumbnail. Welcome back btw!
ОтветитьHe's back 🎉🎉
Ответитьoh my boi is back
ОтветитьMate, Dark theme please.
ОтветитьBest lighting on the tubes, welcome back!
ОтветитьWe need more of these interview tips gems
ОтветитьNice lighting😊😅
Ответить😎
Ответитьfirst one to watch!
