IntelliJ IDEA

IntelliJ IDEA is a JetBrains product. We will use the Community Edition, which is open source and a fantastic tool with which to code Java and Kotlin. The tool offers a fantastic autocomplete feature, and also fully supports Java 8 features.

Go to https://www.jetbrains.com/idea/download/#section=linux and download the Community Edition. We can extract the tar.gz and execute it.
