In two days, all the essentials of Kotlin will be taught to be able to start working on a back-end service written in Kotlin. You will also get familiar with some of the more advanced constructs like coroutines and the ecosystem. The trainer will help you get familiar with popular tools and frameworks as well. Next to that, there will be a focus on best practices and migration strategies to Kotlin from Java.

Detailed description
After these 2 days of training you will be able to read and write Kotlin code on your own, understanding its idioms. Important language features such as data classes, extension methods, inheritance DSL languages will be discussed and you will learn to work with them through exercises. You will be able to confidently write a Kotlin application built in Maven and use Spring in combination with Kotlin after day one. On the second day, more advanced language features such as scope functions and coroutines are explained. Also Kotlin’s ecosystem at the backend side will be introduced. The goal is that you will be able afterwards to design a whole Kotlin application yourself. Part of the day will also be spend on migrating towards a Kotlin application from Java and how to apply coroutines and learn about best practices.
