In this talk you will be introduced modern programming language Kotlin. If you’re a Java developer for some years and you’re fed up with NPE, Checked Exceptions, casts and many other things that makes you mad and thinking of becoming a farmer, this talk is for you. Find out that Kotlin is a great solution for these problems. We will talk about differences between Kotlin and Java, key features of this language and how they are implemented, and of course we will read and write code.


– differences between Java and Kotlin

– null safety

– extension functions and properties

– smart casts

– delegates

– lambdas

– let, apply, with, run, also functions

– infix functions

– multithreading and coroutines

– other Kotlin features

In general this talk will try to answer two major questions: “Why do we need to learn Kotlin?” and “How to learn it?” After the break you can become a part of TDD ping-pong session with KotlinTest. Hope you’ll find something interesting for you even if you’re already familiar with Kotlin.
