How to install Oracle Java 16 on Ubuntu 20.04 / 18.04?

Hello, friends. We know that Java is one of the most popular programming languages and now it’s version 16. So in this post, you’ll learn how to install Oracle Java 16 on Ubuntu 20.04 / 18.04

Java is one of the preferred languages by many developers but it is also necessary to run other very important software. In this sense, Oracle from time to time releases a new version that includes good news.

So, if you are a developer and want to try Java 16 on Ubuntu, this post will help you with that.

Install Oracle Java 16 on Ubuntu

The easiest way to install Oracle Java on Ubuntu is by using the PPA of the Linuxuprising people.

In a very brief way, the package is an installer that takes care of downloading the Oracle binaries. Also, it extracts them and copies them in the appropriate directory and everything by us.

So, it opens a terminal or an SSH session.

Once the terminal is started, it updates the whole system:

sudo apt update
sudo apt upgrade

This way we will have the system ready with the security patches to start the installation.

Now, add the PPA repository:

sudo add-apt-repository ppa:linuxuprising/java
Oracle Java 11 (LTS) and 16 installer for Ubuntu (21.04, 20.10, 20.04, 18.04, 16.04 and 14.04), Pop!_OS, Linux Mint and Debian.
 Java binaries are not hosted in this PPA due to licensing. The packages in this PPA download and install Oracle Java, so a working Internet connection is required.
 The packages in this PPA are based on the WebUpd8 Oracle Java PPA packages: https://launchpad.net/~webupd8team/+archive/ubuntu/java
 Created for users of https://www.linuxuprising.com/
 Installation instructions (with some tips), feedback, suggestions, bug reports etc.:

 Important notice regarding Oracle Java 11 and newer: the Oracle JDK license has changed starting April 16, 2019. The new license permits certain uses, such as personal use and development use, at no cost -- but other uses authorized under prior Oracle JDK licenses may no longer be available. A FAQ is available here: https://www.oracle.com/technetwork/java/javase/overview/oracle-jdk-faqs.html . After this change, new Oracle Java 11 releases (11.0.3 and newer) require signing in using an Oracle account to download the binaries. This PPA has a new installer that requires the user to download the Oracle JDK 11 .tar.gz and place it in a folder, and only then install the "oracle-java11-installer-local" package. Details here:  https://www.linuxuprising.com/2019/06/new-oracle-java-11-installer-for-ubuntu.html
 About Oracle Java 10, 12, 13 and 14: These versions have reached the end of public updates, therefore they are longer available for download. The Oracle Java 10/12/13/14 packages in this PPA no longer worked due to this, so I have removed them. Switch to Oracle Java 11 or OpenJDK 11 instead, which is long term support, or the latest Java 16.
