We are happy to announce our joint JUG UA, Kyiv Kotlin User Group, JEEConf meetup!

Date: May 17, 18:00 – 22:00 (registration from 17:30)

  • Reactive Spring (Juergen Hoeller, Josh Long @ Pivotal)

Spring Framework 5 is here ! It introduces the Spring developer to a growing world of support for reactive programming across the Spring portfolio, starting with a new Netty-based web runtime, component model and module called Spring WebFlux, and then continuing to Spring Data Kay, Spring Security 5.0, Spring Boot 2.0 and Spring Cloud Finchley. Sure, it sounds like a lot, but don’t worry! join us, your guides, Spring co-founder and Spring Framework lead Juergen Hoeller and Spring developer advocate Josh Long, and we’ll explore the wacky world of Reactive Spring together.

  • Multiplatform development with Kotlin (Dmitry Jemerov @ JetBrains)

In Kotlin 1.2, we’ve added support for developing multiplatform projects. Multiplatform projects allow you to reuse the business logic written in Kotlin between all the components of your application – backend code on the JVM, frontend code in JS, and also mobile apps. The common code is compiled for all platforms and can access platform-specific implementations of APIs and libraries. The platform-specific parts are also written in Kotlin and have access to the full set of features of the corresponding platform.

  • Cool after-party!!!

  • 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.
 – 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.
