Agenda

  • Kotlin for Java developers: How and Why (Marharyta Nedzelska @ Luxoft) slides, src, video
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.
Agenda:
 – differences between Java and Kotlin
 – null safety
 – extension functions and properties
 – delegates
 – destructuring Declarations
 – lambdas
 – let, apply and with functions
 – infix functions
 – other Kotlin features
 – testing with KotlinTest
In general this talk will try to answer two major questions: “Why do we need to learn Kotlin?” and “How to learn it?”
After a small break you can become a part of TDD ping-pong session with KotlinTest. So take your laptop with you! Hope you’ll find something interesting for you even if you’re already familiar with Kotlin.
