Hello guys, If you are in Android application development or server-side Java development, then you might have heard about the Kotlin programming language, created by JetBrains, the company behind popular IDEs like IntelliJIDEA, PyCharm, and WebStorm. Kotlin is also Google's official language for developing Android apps. If you don't know what Kotlin is and why you should learn Kotlin, then let me tell you that Kotlin is a mature programming language that offers many benefits over traditional programming languages like Java which has been time-tested over the last 25 years. Kotlin is designed to solve pain points of Java programming language like verbose nature and boilerplate.
Kotlin has been around for quite some time now, but it really took off since 2017 when Google chose it as the official programming language for developing Android apps. That brings a lot of interest from both Java and Android developers to learn Kotlin, and why not? It's fully compatible with Java, and what you can do in Java in 20 lines is that in 5 lines in Kotlin.
In fact, I have been recommending Java developers to learn Kotlin and have shared some books and courses to learn Koltin as well, which was liked by many of you, but there was also a request to share more free resources like books, tutorials, and courses.
Earlier, I shared the best courses to learn Kotlin in 2024, and today, in this article, I will share some of the best free online courses to learn Kotlin in 2024.
I have collected these courses from different websites online like Udemy, Pluralsight, Coursera, and it even has a lesson from Google for learning Kotlin for absolutely FREE.
You can use these courses to learn Kotlin programming language, basic and advanced concepts, and server-side Java development alongside Java and creating Android apps where Kotlin really sees a lot of traction.
Btw, If you don't mind paying a few bucks for learning a valuable skill like Kotlin, then I highly recommend you check out Kotlin for Java Developer course on Udemy, which is both comprehensive and very engaging. You can use this course to learn Kotlin for server-side Java development and mobile app development with the Android platform.
Don't think that because they are free means they are of inferior quality. They are made accessible by their instructors for educational and marketing purposes, and they are actually top-quality online training courses.

Thank you, I have joined the first kotlin course in this list and I am loving it.
ReplyDeleteHow long does it take to learn Kotlin? I know Java but I have not done a lot of functional programming.
ReplyDeleteIs learning Kotlin really worth the hype? I am seeing a lot of conversation on Twitter where people are advocating Kotlin over Scala, especially given it can be used for frontend and backend but I am not convinced yet. I think there are fewer jobs for Kotlin developer than Java developers so sticking with Java makes sense to me.
