Kotlin Guide


my name is Thorsten Schleinzer and I am the author of the Kotlin Guide.

I am a professional software developer for more than 20 years now, mainly working with Java and now Kotlin, which turned out to be my language of choice today.

In the Kotlin Guide, I would like to tell you why I am so excited about Kotlin and hope to awake your interest in it.

Of course, you will also learn how to use Kotlin and start writing your first Kotlin code.

Especially if you are an (experienced) Java developer, the Kotlin Guide is for you!

The Kotlin Guide is work in progress! So quite a few pages are not done yet and typos are all around. There are a lot of topics still on my todo list, waiting to be written about and published. So you are more than welcome to check now and then to learn new things about Kotlin.
