I really wished i studied in the US. You guys really have the gift of presenting and explaining something in a way no other can, hands down to you Jason and to your fellow citizens.

Earned my sub with the meatball joke, I thought about him when you were explaining the abstraction of "animal" without any definition/conformity to variables

I'm taking the Stanford CS106A online course, and it's been great so far (learning a ton of stuff...). But the only thing I really couldn't get my head around was the way interfaces actually work. Even the almighty book ("The Art & Science of Java") didn't give a clear enough insight on the subject. Your 20 min video just did a magic trick on my brain! Thanks a lot!!

Thanks, fantastic explanation! Also really good that you added the "Compiler enforced standardization" part. Because I didn't understand why it made sense to add extra restrictions (when using interfaces) if you had to define the methods in the class anyway. Nice if things make sense. :)

This is a very useful and clear explanation. I do have one question, though: why is multiple inheritance supported for interfaces but not for classes? I understand the diamond problem with multiple class inheritance, but why is this no longer an issue when you try to implement multiple interfaces?

Note that you can provide implementation in an interface if you use the key words default or static. Also, interfaces can extend other interfaces(not sure if that was mentioned).

@johnvictorengland7703 5 жыл бұрын

Can you just use super(); to call the constructor of the abstract class? //nevermind this - the video answered the question already - no you cannot. It's not meant to be run. By the way, this is a great video on Abstract classes and interfaces. So much better than any other video out there on youtube. In fact in 26 minutes you made this crystal clear for me.
