Install Java on Ubuntu 20.04

In this tutorial, we will show you how to install Java on Ubuntu 20.04. For those of you who didn’t know, Java is a programming language and computing platform. It was first released by Sun Microsystems in 1995. Many programs and scripts require Java to run it, but usually, Java is not installed by default on a VPS or Dedicated Server.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges.
