However Kotlin language first appeared on 2011. First stable Kotlin version was released only on 2016, so as you see it was developed for really long time until matured to reliable complete language. Sounds good? Another question that comes to my mind is if Kotlin is already finished language, can we trust it to use in real life projects? You know sometimes to rush and chase the latest technology is not the best idea while it’s just half-baked. It is is designed with the idea to be just a better language than Java. Meanwhile Kotlin is really modern, with it you can write more safer and more functional code which besides being shorter manages to do more than written in Java. We all know that Java is already old language which is not changing a lot and fast enough, so it don’t have modern programming language features compared to other languages. Main question for me was why the hell do we need Kotlin when we have already reliable and one of the most popular language in the world Java? Answer here is so predictable. I won’t lie, I had all these myself, but after some research managed to find all the answers. In this post I will share my findings on Kotlin and show you how to build small Android calculator app using this new language.īut first lets talk about any questions or doubts that could developer have to start using Kotlin. So there are no more excuses to make for not learning it. This is new programming language from JetBrains which has been announced as official Android development language during Google I/O 2017 event.
