Installing Scala on your computer
An excellent resource for Scala installation on your computer is the Scala official page at https://www.scala-lang.org/download/. It mentions how important it is to make sure that Java JDK 8 is installed on your machine. This can be checked by running the following command:
$ java -version
If it is missing or if you have an older version of JDK, please follow the instructions on Java SE downloads from https://www.oracle.com/technetwork/java/javase/downloads/index.html for your OS. Open JDK (http://openjdk.java.net/install/) is another resource for installing JDK.
Please note that a higher version of Java might work fine as well; however, the examples provided in this book have only been tested on Java 8.
A successfully installed JDK 8 should output something similar to the following code:
$ java -version
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)
$ javac -version
javac 1.8.0_181
