Until last year, I was suggesting Java developers learn Scala because of its impressive list of functional programming features, but 2023 is different. Not just for Android development but also for creating server-side applications. It's the best course for any Java developer, both beginners and experienced who want to learn Kotlin.

Btw, if you are in a hurry and just want to start with the best course, you can check out Kotlin for Java Developers on Udemy. If you don't know, Kotlin generates bytecodes, which can run in JVM, which is what makes it 100% compatible with Java. If you know, Kotlin was created by JetBrains, the company behind IntelliJ IDEA and they designed to reduce Java boilerplate code and have some of the goods from functional programming paradigm, but, they couldn't rewrite all their IDEs in Kotlin from scratch, they made sure that it remains 100% compatible with Java. It allows you to auto-generate getter, setter, equals, hashCode, toString, and much standard stuff, you don't need to write that on your own. What you can do in 100 lines of code in Java can be done in just a few lines in Kotlin. So, if you are a Java developer with a passion for writing Android apps or want to reach the masses to promote your next startup idea, you should learn Kotlin.īut if you don't have an interest in mobile development, then also you can learn Kotlin because it improves your productivity while it remains 100% compatible with Java. Kotlin is now the official language for Android app development. It will not only widen your thoughts but also make you a better developer, and that's why I recommend every Java developer to at least learn one more JVM language, and Kotlin is a good one to start with. Well, to be honest with you, being a Polyglot programmer, like a programmer who knows more than one programming language, is an essential and distinguished skill. Or which one is better to start with Android development, Kotlin, or Java? I have already answered that question in my previous article, but I am still receiving a lot of queries about learning Kotlin and whether Java developers should Learn Kotlin or not?
