The Kotlin linguistic communication lets y'all create apps inwards less time, writing less code, together with amongst fewer errors.
This modern object-oriented linguistic communication offers a rigid type system, type inference, null safety, properties, lambdas, extensions, coroutines, higher-order functions, together with many other features. Kotlin is together with thence concise that y'all tin create consummate information classes amongst a unmarried work of code.
Kotlin is officially supported for edifice Android apps, fully interoperates amongst the Java programming linguistic communication together with libraries, together with is included amongst IntelliJ together with Android Studio.
In this course of written report y'all volition larn everything y'all take away to computer programme inwards Kotlin, including:
Basics: Write Kotlin statements together with expressions inwards the IntelliJ REPL Kotlin interpreter using nullable together with non-nullable variables, information types, operators, together with command structures.
