I just dropped the plan to learn kotlin because lack of some good resources but when i found your tutorials i am again putting my hands on it. Awesome experience in your tutorials.

@thomasbartke 4 месяца назад

Awesome and very clear explanation! Thank you! The only thing you skipped is talk about why Kotlin (as opposed to Java) only allows a single abstract method in an interface. Still looking for that explanation...

This guy knows how to irrigate his community of developer herds with knowledge. Highly recommend for new pie and experienced java developers. Kotlin is more fun than java.

Thank you, and I will dream about the word "simply" for a year now. I may never recover after this.

What an awesome explain!!! #Respect the lecturer

@vladopris1172 4 года назад

If one class can inherit 2 interfaces, and solve the diamond problem by calling super.commonMethod(), why not a class can inherit 2 normal or abstract classes and solve the diamond problem with the same solution?

I like how he says "This compiler is not happy" whenever the compiler throws an error lol

thank you

@blackballization 4 года назад

In java it's allowed to create instance of the interface why it's not the same to java?

How to take refernece of interface in variable

@GameCrawl 3 года назад

so what is the difference between abstract class and interface?

@freecountdummy4623 4 года назад

Hi, I'm new in kotlin. I get confused about "Interfaces in Kotlin can contain declarations of abstract methods, as well as method implementations. What makes them different from abstract classes is that interfaces cannot store state" What does that means? what is different between method with body in interface and abstract class? Thank you for such a great video

@feepin2058 4 года назад

Well it means that abstract classes can hold datas while interfaces are just bunch of methods

@engmohamed6819 3 года назад

Good job, but I think each property in interface is open if u initialize it but when u create it without initialization it will be abstract by default. But when I practice I found that interface can’t hold any initialized value but it can hold function with body I don’t know why. So if u know why I’ll appreciate your explain. :)

@code8294 2 года назад

Because Properties declared in interfaces can't have backing fields

@tadiyal04 4 года назад

Hi Sriyank i have query, if we have two interface with same abstract method when we implement these two interface than override that method is going well but when i run app its showing error( Exception in thread "main" kotlin.NotImplementedError: An operation is not implemented: Not yet implemented )

@pranavsubramanian2549 2 года назад

Because of TODO("Not yet implemented") you must remove this line
