Java 8

Installing Java 8 on your machine

Note: This tutorial is made for Linux users because they are the most likely to not have the correct version of Java pre-installed. If you are not a Linux user but are still facing issues and/or are uncomfortable using the Command Line/Terminal please ask for help.

Open the terminal and check to see which version of Java is installed:

$ java -version

If the resulting output looks like this: openjdk version "1.8.0_171" Then the correct version of Java is installed and you do not need to make additional changes. If you see this output, but are still facing issues, go here.

In the rare case that Java is not currently installed on your machine, you will see the following output: Command 'java' not found

You will need to install OpenJDK: $ sudo apt install default-jre

Install Java 8 by executing the following command:

$ sudo apt install openjdk-8-jdk

Check to see if the Java 8 was installed correctly:

$ java -version

The resulting should look like this: openjdk version "1.8.0_171"

You now have Java 8 installed and running.
