Kotlin is an open-source statically typed programming language that targets the JVM, Android, JavaScript, Wasm, and Native. The project began in 2010 and was open source from very early on. On the other hand, Java has been round since 1995 and is among the most widely known languages. Many developers be taught it as their first programming language. While this will result in extra boilerplate code, it also makes the language extra specific, which might help new builders higher perceive what the code is doing. Java’s object-oriented programming model is evident and simple to grasp, which aids in studying foundational programming ideas.

Transitioning From Java To Kotlin

This ensures higher compile-time checks and helps stop null pointer exceptions throughout runtime.

  • Since both Kotlin and Java run on the JVM, they will both be used for developing Android apps, net companies, and enterprise functions.
  • It exists in variants thattarget the JVM (Kotlin/JVM), JavaScript (Kotlin/JS), and native code(Kotlin/Native).
  • Since the value of “Kotlin” is of kind String, the compiler infers thatlanguageName is also a String.
  • See What’s new in IntelliJ IDEA for the latest updates and improvements for Kotlin.
  • Well, tie is the final word result of this comparison as both languages have related learning curves.

The concept is good, however placing it into follow is ultimately most important.

The Create a multiplatform app using Ktor and SQLDelight – tutorial guides you properly on this course of. Rough estimates point out approximately a 40% minimize in the variety of lines of code. It’s additionally extra type-safe – for example, assist for non-nullable varieties makes functions less vulnerable to NPE’s. Other features including smart casting, higher-order capabilities, extension capabilities, and lambdas with receivers present the power to put in writing expressive code as properly as facilitating creation of DSL.
