Java is a popular language without any doubt. And, developers around the world are enjoying making code in Java as it’s one of the most important tools for the Android App Development. Yes! Java is everywhere. Java is object-oriented, class-based and runtime environment (JRE) that let Java developers to Write Once, Run Anywhere (WORA) on all Java-supportive platforms without the need of recompilation. But now the time has changed, in the smartphone-driven world, we all need some advancement and modern language or technology for mobile app development. Before diving into it, you need to know why? Why new technology is defeating the old one?

However, there is one modern and advanced programming language, i.e. Kotlin, which Google has officially adopted as the supported language for mobile app development. It was developed by JetBrains. A long time ago, at Google’s last I/O conference in 2017, Kotlin received huge applause and cheerful admiration from Android developers and rose as a compelling new programming language for Android Application Development.

Although, there are various mobile app maker tools available in the market that are holding their position for a specific purpose. These frameworks are Ionic, React Native, Xamarin, PhoneGap, Flutter and so forth.

Remember that if you are completely new in programming and wants to learn programming Android Development, then you should go with Java. But if you are experienced developer in Java development and wants to switch to a new trending programming language, then you can choose Kotlin.

So the question is that Kotlin VS Java, which is best for Android App Development?

It’s very hard to say that which is best, but the truth is that Java is ruling the entire world even universe, while Kotlin has emerged as the most loved programming language among Android developers.

Both the languages have their separate fanbase. Developers’ perception of Kotlin and Java are different or even change person to person. But if talk about figures, Kotlin has hogged the limelight of Java and continues to rise in popularity in terms of mobile app development.

So here we have decided to talk a little about each language.

  • There is Anko Library is also available for Kotlin.
  • Kotlin Beats Java in Data Classes

Downsides of Kotlin

  • In a comparison of Java, it shows a slower compilation speed.
  • Lake of resources
  • Limited learning resources
