If you want to become an Android developer and are confused about whether you should learn Java or Kotlin in 2024 then you have come to the right place. In the past, I have shared the best Android courses and the best Java courses for beginners, and today, I am going to answer this pressing question for you. Ever since Google announced Kotlin as the official language for Android development in Google IO 2017, programmers who want to become Android developers are in a dilemma. Now the big questions in front of them are whether they should learn Kotlin or Java in 2024? The answer to these questions depends upon your profile.
If you are a complete beginner who wants to learn Android development, then my answer is Java, but if you are a Java developer who wants to jump into the lucrative market of Android App development, then my answer is Kotlin. I'll discuss why a beginner Android programmer should start with Java and why a Java developer should learn Kotlin in this article.
When I said, beginners should start with Java, you might be thinking what the heck, Kotlin is much more productive, less boilerplate code, and now the official language of Android Development and this guy is suggesting learning Java, I am not gonna fall for it...
Well, being a Java developer, I may be a little bit biased, but I'll try to explain my reasons why I suggest a beginner Android developer start with Java rather than Kotlin, but if you have already made your mind to learn Java then you can skip this article now and straight go to The Complete Java MasterClass to learn Java in depth.
It's one of the most comprehensive and up-to-date courses to learn Java online. It has recently been updated to cover the latest features introduces in Java 9, Java 10, and subsequent releases. If you want to learn Java, that's the course I recommend. Now, if you haven't made your mind yet, read on.
The second and more important thing is that there is a massive community of Java programmers, which means you can find answers when you are stuck. This is very important because as a beginner you will face a lot of technical problems and you might not know where to head when you are held.
When you search Google with a Java problem, you will bound to get answers; the same cannot be said for Kotlin, which is still a new programming language.
There are also more tutorials, books, and courses out there, both free and paid, which can teach you Android development with Java-like this list of Android resources for Java programmers, but there are not many for Kotlin, especially free resources on Android development.
Things will definitely improve over time when more and more programmers will start using Kotlin, but I doubt it can ever touch the popularity and adoption of the Java programming language.
That's why I suggest a beginner programmer who wants to become an Android developer to start with Java, rather than Kotlin.
But, that's not a hard and fast rule; if you prefer learning Kotlin rather than Java due to productivity reasons and mostly focused on Android development, then you can sure start with Kotlin, and Android Kotlin Development Master Class is the right place, to begin with.
But, once you know Java, your journey to Kotlin will also be easy and smooth because Kotlin is 100% interoperable with Java. It compiles into Java bytecode and runs on JVM. To start with you can check out that course and if you need more choices you can always look at this best Kotlin online courses article to find more options.
A class that takes 50 lines of code in Java can really be written in just one line in Kotlin. It can help you avoid all boilerplate code for you like you don't need to specify getters and setters, equals(), hashCode(), or toString() method. Kotlin can generate all that by itself.
Here is a nice comparison between Kotlin and Java in terms of productivity and lines of code to write similar stuff:
If you don't know, Kotlin was developed by JetBrains, the company behind one of the most popular Java IDE, IntelliJ IDEA. They were a Java shop and developing IDEs like IntelliJ IDEA, PyCharm, ReSharper all in Java and built Kotlin to improve their productivity, but at the same time, they cannot rewrite all their code in Kotlin, and that's why they made Kotlin fully interoperable with Java.
Because Kotlin generates Java bytecodes, you can use your favorite Java frameworks and libraries in Kotlin, and your Java friend can also use any Kotlin framework you develop. Even the dominant Java framework like Spring has started supporting Kotlin from Spring 5. If you don't know what's new in Spring 5, check this out.
Even though currently, almost all Android codes, examples, apps are in Java, it will change in the future because Google has declared Kotlin as the official language for Android App Development.
Many companies have already started using Kotlin for their Android app development, and that's the main reason I think Java developers should learn Kotlin
If you decided to learn Kotlin, then Kotlin for Java developers course from Udemy is the right place, to begin with. It's a no-nonsense course for Java developers, which will help you to get going with Kotlin in no time.
You don't need to start with things like what is a variable and object as this course has the right pace and depth for Java developers as compared to other beginner Kotlin courses for Android development.
If you prefer books, then Kotlin in Action is also not bad. You can learn about all the essential features of Kotlin, like var vs. val, data keyword, and functional programming stuff all by yourself.
That's all about whether Android developers should learn Kotlin or Java. As I said, if you are a complete beginner who wants to start your career as an Android developer, you better start with Java. You not only get up to speed in no time but as you would have better community support and knowledge of Java will help you a lot in the future. It will also help you to learn Kotlin in the future.
And, if you are a Java developer, then you better start learning Kotlin to not only improve your productivity but also help you become part of a lucrative niche of Java developers who know Kotlin, which may give you a competitive edge in the job market.

Awesome blog! Do you have any recommendations for
aspiring writers? I'm planning to start my own website soon but I'm a little lost on everything.
Would you advise starting with a free platform like Wordpress or go for a paid option? There are
so many options out there that I'm completely overwhelmed ..
Any ideas? Thank you!
