How to install Kotlin on Ubuntu 22.04

Hello, friends. In this post, you will learn how to install Kotlin on Ubuntu 22.04. This modern language is intended to replace Java in key processes of Android and other components where it reigned supreme.

According to the Kotlin website:

Kotlin is a modern but already mature programming language aimed to make developers happier. It’s concise, safe, interoperable with Java and other languages, and provides many ways to reuse code between multiple platforms for productive programming.

One of the great advantages of Kotlin is that it aims to simplify many of the things that Java has not been able to. This makes it a bit of lighter, and it is also being considered as a replacement.

Kotlin can be used as a backend language, frontend language, to make libraries and even as a scripting language. So, it is very flexible for many things.

Moreover, it even works with the JVM, so it will run on almost any current operating system.

Kotlin is included in each IntelliJ IDEA and Android Studio release. So, downloading and installing some of these two IDEs will make the whole process easier, but what if we don’t want to? Well, we can download and install the compiler manually.

sudo apt install openjdk-11-jdk

The next step is just to install Kotlin using Snap. This way is one of the easiest and most straightforward.

sudo snap install --classic kotlin

Sample output:
