Why Companies Prefer Kotlin Over Java for New Projects

Kotlin = Cleaner Syntax, Less Boilerplate, Same Bytecode

If you look at code written in Java and then compare it to equivalent code written in Kotlin, you’ll notice a few things:

  1. The syntax is remarkably similar. For Java developers, Kotlin is easy to learn and intuitive to use.
  2. One key difference is how variables get declared. Kotlin is a statically-typed language, but it can infer types or you can set them yourself. Ultimately, this means less boilerplate code like Java’s public void or Person person = new Person()
  3. You’ll notice that Kotlin code is much shorter and cleaner. For example, Kotlin supports data classes with built-in getter and setter methods so you can do Person.name instead of having to implement and use Person.getName()

Resolves Known Issues with Java

At the same time, Kotlin’s less verbose syntax is more type safe. For example, Kotlin has non-nullable types that will raise a compilation error, leading to reduced occurrences of the dreaded Java NullPointerException.

Biggest Growth Area: Kotlin for Android with Google’s Support

The major reason Kotlin is growing so quickly is Google’s support for using Kotlin when creating Android apps. Since Kotlin compiles to the same bytecode as Java, you could always use Kotlin to build Android apps. However, with Google’s official seal of approval came attention, tooling, open source packages, and integration support for Kotlin code throughout the Android ecosystem. Most notably, Android Studio has a suite for Kotlin tooling and build.

Make the Switch Gradually

Kotlin’s interoperability means that you don’t have to rewrite existing Java applications. You can add Kotlin into your code base gradually and it will play nice with your Java code. This is an attractive option for many companies because Kotlin is easier to use, but they don’t have the time/resources to rewrite an entire code base.
