With the undisputable notoriety of Java as a programming language, Android was found wanting a cutting edge language to compete. Kotlin filled that hole no sooner it was declared as the official language for Android development. So, I am writing this blog on Kotlin vs Java in order to help you spot the major differences between them.
I’ll be discussing the topics in following order:
Kotlin is officially supported by Google for mobile development on Android. Ever since the release of Android Studio 3.0 in 2017, Kotlin was included as an alternative to the standard Java compiler.
Talking about the importance of this language, it is the most strongly supported JVM language in the Android ecosystem, aside from Java. With Kotlin you can write significantly less code when compared with Java. Fewer lines of code imply smaller file sizes for Kotlin, compared to Java equivalents.
Java is one of the oldest and easiest languages. It has been at the top for more than two decades and it is still a very popular programming language. It is an object-oriented programming language developed by Sun Microsystems, which is currently owned by Oracle.
Java does a whole lot more than just develop Android applications. So if you know your way around Java, you become a part of the bigger Java community and market, hence you have a lot more career opportunities.
This is a reputable programming language. It is mainly:
Now that you’ve got a gist of what is Kotlin and what is Java, let’s discuss the parameters to compare Kotlin & Java.
I will consider the following parameters to compare Kotlin vs Java.
Java’s compilation time is comparatively fast.
Kotlin has inbuilt null safety. The not so famous NullPointerException is largely responsible for Android development mistakes. Android mainly relies on Null to represent the absence of a value, but it can easily destroy an application. Kotlin easily solves this problem by incorporating inherent null safety. Due to this addition, many developers are saved from writing extra code to work around the issue.
Java’s code development speed is comparatively faster.
Kotlin supports Lambda expressions which are essentially anonymous functions that can be treated as values. You can pass them as arguments to methods, return them, or do any other thing you would do with a normal object.
Kotlin has limited learning resources as it is a small and new community.
Java is a vast programming language so the community circle is bigger than Kotlin.
|Compilation time||Slow||Pretty fast|
|Development speed||Fast||Faster than Kotlin|
|Community support||Limited||Very large|
Kotlin vs Java: Advantages of Kotlin over Java
Kotlin is interoperable with Java, which means that you can leverage all existing Java libraries, JVM, and the frameworks.
This helps in drastically reducing the amount of boilerplate code in your project.
The developers who know Java can easily learn Kotlin. Switching from Java to Kotlin does not have much overhead and adapting to it doesn’t possess any cost.
Now let us talk about the disadvantages of Kotlin.
Now, I’ll answer your most frequently asked question, is Kotlin going to replace Java? The answer is no. Kotlin has powerful features and so does Java. They both bind together to treat us with more improvised versions. So, yes, Java and Kotlin go hand in hand for android development.
This brings us to the end of this article where we have discussed the major differences between Kotlin and Java. Hope you are clear with all that has been shared with you in this tutorial.
