Can I use Kotlin for Android development? People are using Kotlin for mobile and server-side applications, client-side with JavaScript or JavaFX, and data science, just to name a few possibilities. With Kotlin/Native currently in the works, support for other platforms such as embedded systems, macOS and iOS is coming. Kotlin can be used for any kind of development, be it server-side, client-side web and Android. There's also an automated Java-to-Kotlin converter built into the IDE that simplifies migration of existing code. This makes adoption much easier and lower-risk. You can easily call Kotlin code from Java and Java code from Kotlin. Kotlin is 100% interoperable with the Java programming language and major emphasis has been placed on making sure that your existing codebase can interact properly with Kotlin. Is Kotlin compatible with the Java programming language? Other features including smart casting, higher-order functions, extension functions and lambdas with receivers provide the ability to write expressive code as well as facilitating creation of DSL. It's also more type-safe, for example, support for non-nullable types makes applications less prone to NPE's. Rough estimates indicate approximately a 40% cut in the number of lines of code. What advantages does Kotlin give me over the Java programming language? With first-class support for features such as higher-order functions, function types and lambdas, Kotlin is a great choice if you're doing or exploring functional programming. You can use it in both OO and FP styles, or mix elements of the two. Kotlin has both object-oriented and functional constructs. Is Kotlin an object-oriented language or a functional one?
