Install Oracle Java 8 on Ubuntu

How to install Oracle Java 8 on Ubuntu (in my case, Ubuntu 16.04 LTS)

Procedure to install Oracle Java 8 on Ubuntu

You probably want to confirm first that a version of Java is not already installed. If so, you can do that with the java -version command as shown below…

developer@ubuntu:~$ java -version The program 'java' can be found in the following packages: * default-jre * gcj-5-jre-headless * openjdk-8-jre-headless * gcj-4.8-jre-headless * gcj-4.9-jre-headless * openjdk-9-jre-headless Try: sudo apt install developer@ubuntu:~$

Change to root…

sudo su - (enter password) apt-get install software-properties-common add-apt-repository ppa:webupd8team/java apt-get update apt-get install oracle-java8-installer

Check if Java is successfully installed

java -version java version "1.8.0_111" Java(TM) SE Runtime Environment (build 1.8.0_111-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)

Procedure to uninstall

If, for some reason, you want to undo this operation and uninstall Oracle Java 8 from Ubuntu, you can then execute the following:

sudo su - sudo apt-get remove oracle-java8-installer
