It wasn’t very pleasant to read as it is indeed just a reference, not an explanation about why things were defined the way they are. Read the documentation reference ( also available in PDF), it is 100% free. Do the Kotlin Koans to check what Kotlin is all about. Official documentationįirst, just try it out.

I will learn this mysterious new language! The question is how? Here’s my path, and I hope it will help you to start with Kotlin as well. I was genuinely happy to hear this news because now companies will be much more inclined to let us, tech people, use it in production as Google backs it up. I heard about it a long time ago but didn’t try it until Google announced Kotlin became a first class citizen language on Android. The problem in this portion of the tutorial was to take this Java code and rewrite as Kotlin code.Kotlin is a new programming language for the JVM, Android, Javascript, and in the near future, native (iOS, Windows). Of course, I wanted to do the exercise myself so that I can get the hang of writing Kotlin code. I thought this was incredibly slick because it gave me the change to see the differences between Java and Kotlin. You can see in the video that IntelliJ just did the work of taking the Java code that I copied and pasted into my Kotlin class. When you copy and paste Java code into the IDE, it will offer to translate it to Kotlin for you. It was IntelliJ’s support of Kotlin that blew me away. It wasn’t that I was super impressed with the language itself. When I moved onto part two of the tutorial, I was really impressed.

Nevertheless, I decided to continue with the Kotlin tutorial found at.

After doing the first tutorial on Kotlin, I was impressed, but let’s face it, anyone can do a simple “hello world” style program.
