Top 5 Kotlin Online Courses for Java and Android Developers in 2024 [UPDATED]

Hello there, If you want to learn Kotlin and looking for the best online courses then you have come to the right place. Earlier, I have shared the best Java courses for beginners and the best Android Courses and today, I am going to share the best courses to learn Kotlin in 2024. You might have heard about Kotlin and how it's becoming the standard language to develop Android applications, but it's much more than that. If you don't know Kotlin, it's a relatively new programming language that makes programming for Android and Java easier. Ever since Google announced Kotlin as the official language for Android Development, I have received a lot of queries from my readers about whether Java developers should learn Kotlin now? 

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?

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. 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.

Kotlin is now the official language for Android app development. 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.

But 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.

What you can do in 100 lines of code in Java can be done in just a few lines in Kotlin. 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.

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.

If you don't know, Kotlin generates bytecodes, which can run in JVM, which is what makes it 100% compatible with Java. 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. It's the best course for any Java developer, both beginners and experienced who want to learn Kotlin.  Not just for Android development but also for creating server-side applications.

5 Best Kotlin Training Courses for Beginner Android Beginners in 2024

Until last year, I was suggesting Java developers learn Scala because of its impressive list of functional programming features, but 2024 is different.

This is the year to learn Kotlin because I expect Kotlin to surpass Java for Android development in a few years because of its distinguished position of being an official language for Android development.

In this article, I am going to share some of the best online courses to learn Kotlin from scratch. The classes are divided into two categories, first, which teaches Android development with Kotlin, and second, which shows the Kotlin programming language itself. You can choose a course which suits your requirements. 

1. Kotlin for Java Developers

If you are a Java developer who wants to learn Kotlin and enhance your career prospects, then this is the perfect course for you. It allows you to use your Java skills to learn Kotlin faster.

I strongly suggest Java developers learn Kotlin, not just for Android app development but also as a skill that they will use in the near future.

Since Kotlin works anywhere Java works, and can even be called from Java code (and vice-versa), this brings with it a massive opportunity for Java developers. Being able to work with both Java and Kotlin is going to give you an enormous advantage over all other programmers.

This is a no non-sense course that has the right kind of pace and depth needed for experienced Java programmers. It was specially designed to teach Java developers how to use Kotlin in the shortest possible time.

Sarah Eldritch, an instructor of this course, is an experienced Java and Kotlin developer, which makes her qualified to teach you this powerful and exciting language in a quick time.

In short, a perfect course for Java developers to learn Kotlin, and also the critical differences between Kotlin and Java. I have recently purchased this course for just $9.99 in Udemy's flash sale, which is seriously a bargain.

2. The Complete Kotlin Developer Course [Udemy Course]

This online Kotlin training course is the best of both worlds, it will not only teach you Kotlin programming language but also how to develop Android Apps using Kotlin.

You will learn about variables, strings, and other data types in Kotlin and Essential programming constructs, like conditionals, for loops, Maps, Functions, classes, Nullables, etc.

You will also learn how Kotlin and Java are related to each other.

In short, an excellent online course to learn Kotlin basics along with its practical use for developing Android Apps. Going forward, you should use Kotlin instead of Java and create Java byte code from Kotlin.

The course is created by Rob Percival and Nick Walter, two of the best instructors on Udemy, which means you won't feel bored and sleep while watching this course.

3. The Ultimate Guide to Kotlin Programming [Educative]

This is an ideal course to learn Kotlin from scratch and understand object-orientation and idiomatic Kotlin for Android app development. This course will teach you programming in Kotlin right from the basics, which makes this course ideal for beginners.

After basics, you will learn more advanced Kotlin concepts like lambdas, fluency in Kotlin, and asynchronous programming. In the last section of the course, you’ll take what you’ve learned and build out an Android application that talks to a backend service.

You will put what you learn into practice in several coding challenges. So, in the end, you'll be able to create your own applications in Kotlin. The best thing about Educative courses is that you can practice what you are learning right on your browser, without downloading any software or setting up your environment, where most beginners are stuck. 

If you're an Android developer, you can use this course to get up to speed with this first language. Kotlin will allow you to maintain a cleaner and more expressive code base, use concepts that go beyond even Java 8, and write more robust apps for Android.

4. Kotlin for Android: Beginner to Advanced [Udemy]

This is one of the most comprehensive training courses on Kotlin for Android app development, containing over more than 100 lectures, you will learn almost everything about Android development with Kotlin.

Whether you're a Java developer or have NO Android experience, this course will teach you everything you need to know about how to build apps using Kotlin.

The best part of the course is that it not only teaches you the theory and basics of Kotlin programming language but also teaches you everything about developing with Kotlin, working with interface builders, and all the SDKs and tools you actually need to build apps.

You will develop real-life projects, which is the best way to learn a new programming language or technology.

If you want to make your career in Android application development, then Kotlin is indispensable for you. You must learn Kotlin sooner than later, and this course is perfect to start with.

Also, the Kotlin community is growing, and you have a lot of options to take help, talk to fellow developers, and share your knowledge.
