Debugging the Advantages of Kotlin :
If you compare a Java class and a Kotlin class that produce the same results, the one written in Kotlin will typically be much more succinct and compact than the one written in Java. And as every developer knows, less code means less bugs!
Easy Learning Curve
Kotlin is a modern and Android-compatible language designed to be intuitive and easy to read, with a gentle learning curve. Following that, even if you do encounter some code that’s drastically different, you should still be able to get the gist of what this code is doing.
Moreover, Kotlin amplifies Java and reduces its complexity by making it short, succinct and concise.
Interchangeability With Java
One of the greatest strengths of Kotlin is its sheer level of interoperability with Java. It also gives you the ability to view the code of Java and Kotlin together side by side in the same project without any compromise in compilation.
So, if you have a project you’re working on, you can trial Kotlin in a small part of that project without affecting the rest of your code base.
No Runtime Overhead
The Kotlin’s Kotlin for Android standard library is small and tight: it consists mostly of focused extensions to the Java standard library. Heavy use of compile-time inlining means functional constructs like pipelines of map/filter/reduce compile similarly to an imperative version of the same code.
Fully Supported by Android Studio
Kotlin is developed by JetBrains, the maker of the world’s Best IDEs and the company behind IntelliJ- the IDE that Android Studio is based on. So, it comes with no surprise, that Android Studio has excellent support for Kotlin.
