How To 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. I will show you the step-by-step installation of Java on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

Prerequisites

• A server running one of the following operating systems: Ubuntu 20.04, 18.04, 16.04, and any other Debian-based distribution like Linux Mint.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Java on Ubuntu 20.04 LTS Focal Fossa

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

sudo apt update
sudo apt upgrade

Step 2. Installing Java on Ubuntu 20.04.

Add the “Linux Uprising” PPA via the below command:

sudo add-apt-repository ppa:linuxuprising/java

Once the repository is added, proceed to install Java on Ubuntu Linux:

sudo apt update
sudo apt install oracle-java14-installer

Then, run the following command below to confirm the Java version:

$ java --version

java version "14" 2020-04-20
Java(TM) SE Runtime Environment (build 14+46-1469)
Java HotSpot(TM) 64-Bit Server VM (build 14+46-1469, mixed mode, sharing)
