Poor Andrey, he seems so nervous! Mind you I would be too lol. Great language he created. Many thanks from me, it has made my Android development fun where I have used it. Keep the good stuff coming with Kotlin!
Finally someone fixed Java and made it more C again with other great additions from languages like Python and C# and all that. There a are a *few* quirks I'm not particularly happy about, a lot of them come with the JVM baggage (like not being able to manage my own memory) and I don't understand why we had to switch to name:Type schema instead of "Type name" which I thought was always more natural to read like real text, but I can live with those
Well most of the time you can skip those and maintain code clarity simultaneously. For eg: val obj: MyClass = MyClass() can be turned to val obj = MyClass() without losing any context of the code.
That trick when he showed Kotlin byte code then decompiled to Java was pretty cool. A few months back I was a little confused about what the 'noinline' keyword was doing... this trick would have probably made it clear.
At 22:14, "this is something pretty unfamiliar for the C-language family" ... that is true pre-C++11. But with C++11, there are lambdas and immediately invoked lamba expressions (IILE), so you could write very similar code as follows: auto s = []() { if (condition) { cout
To anyone thinking they are used to Java and don't need to learn Kotlin or struggling, I say go for it learn it trust me all worth it don't think just do it
I learned a little bit of javascript and html then thought "you know what I should do with all of my 6 hours of javascript? Try to make an app in a different language for fun!" So now I'm trying to find a tutorial
Java had annotations for that, and you can and will still get a lot of null crashes now. Even more, actually, since every method where you specify an non optional parameter will crash instantly (Kotlin check) if the said parameter is null. So you need to design clearly each function param....is it optional or not, etc.
The difference is that these crashes occur at compile time and not at runtime, making you think about null safety more that when you just use annotations in java. Its about making you think in a different way about null safety.

Can you just please keep the code on the screen all the time, next time? Maybe just have a speaker view contained in the nested screen...This way I had to stop video too many times.

Any way to avoid this in a short way, and print only if it's not null? 26:34 Any way to convert to normal code instead of lambda? Sometimes it's clearer and seem more flexible...
Continue using Java everyone else will move on and benefit from Kotlin. You are the same person from last year who thinks constant null checks are a benefit.

Readability doesn't mean writing lots of "public static void" or for-loop, it means that you write exactly what you mean. For example, you want to create a new list with each element is two times the element in another list. In Java, you need to do something like `List a = new List(b.size()); for (int i = 0; i < b.size(); ++i) b[i] = a[i] * 2;`. But in Kotlin you only need `val a = b.map { it * 2}.toList;`. And Kotlin version is more readable because it exactly describes what I want to do: creates a new list with each element times 2, but in Java, you need to understand the whole `new` and `for-loop` thing. For more complex logic, it's more difficult to understand what you really mean, i.e. less readability. You may say Java 8 supports lambda function and streams. Yes, Java 8 makes things better, but not good enough.

Not if you use explicit pointers, or whatever they're called in Swift/Kotlin. If you unsafe-unwrap them, they will still crash at runtime
then why use kotlin at all if you are gonna unsafely unwrap the optionals
Great job, master piece. Is the code in the demo available for download anywhere?
Kotlin is really power skills for everyone developer!
