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.
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!
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
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.
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

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.
Base knoledge: js and ts. Typescript (ts) = ts for Javascript (js) Kotlin = ts for Java C++ = ts for C. scss/sass = ts for css. Rust = ts for C++. xml = ts for html delphi = ts for pascal. continue below...
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.

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
do I have to learn or have some idea about java beforehand.
Kotlin's semantics are not tied to the jvm, but some oop experience is helpful
kotlin lang and lib revived the java ecosystem , multiplatform jetpack compose will make it full stack in the full sense of the word

It's time to make a film: forward to the past :)
I don't understand this fight of 'which language lets you write shorter code'. I still find Java more readable.
Agreed. Did we really need 'fun'?
agree
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;`.

pythonic! great
I'm having fun programming in Kotlin, and that couldn't be said about Java.
What is this ide???
Of course it's IntelliJ IDEA by JetBrains: www.jetbrains.com/idea/
Almost good as C#
Hey, can you send me a Kotlin t-shirt :D
Kotlin rocks
very nice!
You've let him talk about basic stuff that one can read by himself in the documentation? I had hoped it would have more depth and would _reveal_ some interesting internal Kotlin things or how they made particular design decisions etc. Disappointing.
Closely to Swift style
Wait take a break n tell...
If I already know Java, why would I learn yet another programming language to do the same stuff in a different way?
Sorry, i didn't liked Kotlin. i will keep with Java, there's no real reason to change.
Thats copied from namedtuple in python
😊😀👍
Ok
Kotlin was inspired by Scala. Or in other words, it stole most of Scala's ideas.
TRANSLATE TO SPANISH PLS!
Umm... Can I have my C#/Java language back now?
👍
Now, I create a 100.000 threads. Looks at the audience as a bad boy.
