Description

Kotlin is a general purpose, free, open source, statically typed “pragmatic” programming language initially designed for the JVM (Java Virtual Machine) and Android that combines object-oriented and functional programming features. It is focused on interoperability, safety, clarity, and tooling support. Programming using Kotlin course is for developers who want to learn the syntax and semantics of the language which is quickly replacing java as the primary language for building Android applications. This course would be a good first course for Java or Non Java programmers to get a good head start in Kotlin.
