A short easy to understand step by step Tutorial on how to download and install Oracle's Java 8 jdk on Ubuntu/Linux using a Terminal.

Note: The Java Version might change in the future, please make sure you update the version number in every command line. For example 1.8.0_112 to 1.8.0_115 or 8u112 to 8u115

1. Step - Download

Note: You may change the link to match newer versions

wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" ht[//remove\\]tp://download.oracle.com/otn-pub/java/jdk/8u112-b15/jdk-8u112-linux-x64.tar.gz

(remove placeholder, youtube likes to shorten links...)


2. Step - Unpacking .tar.gz file

tar -xvzf jdk-8u112-linux-x64.tar.gz


3. Step Creating Java 8 Installation Directory

sudo mkdir /opt/Oracle_Java
sudo mv jdk1.8.0_112/ /opt/Oracle_Java/
