Prerequisite: Introduction to Scala
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:
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 and Installing 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.org
Download 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:
- Getting Started:
- 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.
