Scala 2.12.9

The most popular way to get Scala is either using Scala through sbt, the Scala build tool, or to use Scala through an IDE.


First, make sure you have the Java 8 JDK installed.

To check, open the terminal and type:

java -version(Make sure you have version 1.8.)

(If you don't have it installed, download Java here.)


Then, install Scala:

...either by installing an IDE such as IntelliJ, or sbt, Scala's build tool.

Compared to other programming languages, installing Scala is a bit unusual. Scala is unusual because it is usually installed for each of your Scala projects rather than being installed system-wide. Both of the above options manage (via sbt) a specific Scala version per Scala project you create.

But it's also possible to "install" Scala in numerous other ways; e.g., grab Scala binaries and use Scala from the command line or use Scala in your browser!
