Kotlin

Kotlin is an open-source, general-purpose, statically typed programming language developed by JetBrains team. It is JVM-based and may be used anywhere Java is currently utilized"

There is various IDE available that supports Kotlin project development like, Eclipse, Android Studio, IntelliJ IDEA, etc. We can also use code editors like notepad++, Visual Studio Code, etc. to write our Kotlin code. But for this tutorial series, we will be using IntelliJ IDEA. "

As the Kotlin runs on JVM, it requires a JDK to be installed on your computer. You can download JDK directly from oracle.com but it is not free for commercial use (it is still free for personal use). You have to buy it if you want to use it for production. Therefore we download JDK from adoptopenjdk.net, which is free and open-source.

Before we dive deep into the Kotlin, let’s begin with a simple program that can print Hello world! In console. “Hello World!” printing program is a simple program which is often used to introduce a new programming language." "
