At the latest Google I/O conference, Google made an announcement that Kotlin would now be fully supported by the Android development. This has brought up an entirely new avenue for those people that would like to start creating their own Android applications. Kotlin is highly popular, embedded with a lot of unique features and hence, it creates new opportunities for existing web developers too.

MORE ABOUT KOTLIN

Kotlin is more or less a statically typed programming language from JetBrains. Kotlin is completely ‘inter-operable’ with Java and comes with no drawbacks at all. Kotlin is being used by many of the Android developers today have actually been using Kotlin via a plugin and popular apps on the Play Store that was reportedly created solely using Kotlin. However, as of the forthcoming Android Studio 3.0, Kotlin would be bundled in and supported out-of-the-box.

SOME BASIC SYNTAX OF KOTLIN THAT MAKES IT DIFFERENT FROM OTHER COMPUTER LANGUAGES

  • There’s no public keyword in Kotlin that is because all classes in Kotlin are public and final. There is no need to use extend either, rather a semi-colon would perform the same function similar to that.
  • Instead of writing public void one would be required to write fun. This leads our class a public function that one can call from other classes. Just like Python language, Kotlin is also has been enabled to identify the variable and its type on its own.
  • There’s one more major difference between the two. Kotlin, unlike Java, doesn’t require semicolons. There is no obligation and the coding doesn’t pose a problem while running if you miss one.

There are various differences between Java and Kotlin in syntax; however, the functions and coding of the program can be easily understood with the help of the context.

ADVANTAGES THAT KOTLIN OFFERS

Kotlin solely aims to fill that gap of a modern language that had been missing for a while for the Android platform.

  • Kotlin, unlike other languages, is concise that reduces the amount of boilerplate code one needs to write.
  • It is expressive enough to make the codes more readable and understandable with the help of contexts
  • It is completely safe to avoid entire classes of errors like the null pointer exceptions.
  • Kotlin is quite versatile for creating server-side applications, Android apps or the frontend code running in the browser.
  • The language is interoperable to leverage existing frameworks and the libraries of the JVM with complete 100 percent Java interoperability.
  • The coding of Kotlin is found to be shorter, simpler and more straightforward which makes it easy for a person to identify and understand the codes and various functions.
  • Kotlin is considered to be a more modern language and it might represent a more forgiving learning experience.
IS IT A RIGHT CHOICE TO ADOPT KOTLIN?

Well, this is the biggest question. The question whether Kotlin is the right choice or not totally depends on personal preferences and sensibilities especially when it comes to coding. However, the streamlined nature of Kotlin and its flexibility makes it a preferable choice for many web developers and software engineers.
