How to Install Scala in Linux?

06 Oct, 2021
Prerequisite: Introduction to Scala Before, we start with the process of Installing Scala on our System. We must have first-hand knowledge of What the Scala Language is and what it actually does? Scala is a general-purpose, high-level, multi-paradigm programming language. It is a pure object-oriented programming language which also provides the support to the functional programming approach. There is no concept of primitive data as everything is an object in Scala. It is designed to express the general programming patterns in a refined, succinct, and type-safe way. Scala programs can convert to bytecodes and can run on the JVM(Java Virtual Machine). Scala stands for Scalable language. It also provides the Javascript runtimes. Scala is highly influenced by Java and some other programming langauges like Lisp, Haskell, Pizza etc.Scala is a very compatible language and thus can very easily be installed into the Linux Operating System. The most basic requirement is that we must have Java 1.8 or a greater version installed on our computer.
Verifying Java Packages:The first thing we need to have is a Java Software Development Kit(SDK) installed on the computer. We need to verify these SDK packages and if not installed then install them. Just go to the Terminal and run the following command:
java --version 
Once this command is executed the output will show the java version and the output will be as follows:In case we are not having the SDK installed then download the latest version according to the computer requirements by using the following command:
sudo apt-get install default-jdk
Downloading Scala:Before starting with the installation process, you need to download it. For that, all versions of Scala for Linux are available on scala-lang.orgDownload the Scala and follow the further instructions for the installation of Scala. However, one can easily install latest version of Scala on Ubuntu with the use of following command:
sudo apt-get install scala
Beginning with the Installation:

Starting the Installation Process:
Finished Installation:
After completing the installation process, any IDE or text editor can be used to write Scala Codes and Run them on the IDE or the Terminal with the use of command:
scalac file_name.Scala
scala class_name
Here’s a sample Program to begin with the use of Scala Programming:Let’s consider a simple Hello World Program.
// Scala program to print Hello World!  object Geeks  {     // Main Method      def main(args: Array[String])      {         // prints Hello World         println("Hello World!")      } }
