Today we will learn how to download Scala and then install Scala on Linux, Unix, and Windows OS. Scala runs on top of JVM, so you should have JDK 1.8 or higher version installed all ready to proceed with Scala installation. Since you are here to learn Scala, I am assuming that you know how to install Java on your system.

 

Download and Install Scala on Linux systems

 

Scala installation on Linux, Ubuntu, Mac OS X or any Unix based system is the same, so the below steps should work for any *nix system.

 

Verify the JDK installation on your machine. Open the shell/terminal and type java -version and javac -version.

 

Download and install Scala on Windows OS

 

Download Scala Binaries from http://www.scala-lang.org/download/. As of writing, this post-Scala version is 2.11.8, so you should be getting a downloaded file as scala-2.11.8.tgz. Unzip the scala-2.11.8.tgz file using the following command as shown below.

 

Download and install Scala on Windows OS

 

Now we are in the home directory where Scala binaries are present. Just go to the bin directory.Download and install Scala on Windows OS

 

Now enter the scala shell as shown below.

Scala sample program example:

 

Let us see how to write and execute a program in the shell. Below is a simple class student that we can define in the Scala shell.

 

Download and install Scala on Windows OS

 

Output: defined class Student

 

Here we create a Student class and print the student details in the student details method by passing student id and age as a parameter. If there are no errors in the code, then a message “defined class Student” is displayed.

 

Create the student object and invoke the student details method bypassing the student id and age.

 

Download and install Scala on Windows OS

 

Returns: defined object Stud

 

Now run the code by typing Stud.main(null) and you will see below output as shown in the image.

Intellij IDE:

 

For beginners in scala language, the most popular way to get Scala is either using Scala through sbt, the Scala build tool, or to use Scala through an IDE. By considering you have installed JDK 8 or above, you can install scala by installing an IDE such as IntelliJ, or sbt, Scala’s build tool

 

IntelliJ is an IDE for programmers who want to get started with scala in IntelliJ. You can build a scala project with IntelliJ and sbt. You can also test scala in IntelliJ.
