Where to install JDK .tar.gz file on Ubuntu 18.04?

Where is the recommended place to install the jdk .tar.gz file I just downloaded? I want it to be available for all users.

The installation guides that I have found told me to extract the jdk in many different places, such as /opt, /usr/lib and /usr/local. But the which one is the "right" choice? Why?

First Download the Oracle JDK Download Oracle JDK or Open JdkDownload Open JDK, then follow these commands :

  1. First Unzip the tar file with this following command

For installation from the JDK tar.gz use the following command to unpack the tarball to the desired directory where you need to install java :

tar zxvf jre-8u73-linux-x64.tar.gz

Then you can set the java home by editing the environment file and set java home like :

JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64"

where the latter part is the directory in which you have installed java.Usually java will be installed in the /usr/lib/ .Use an editor like nano or vim to edit the file and add the above key value to set java home.

Into /usr/lib/jvm/ folder, the reason is because the default installation path is that one when you use the sudo apt install command, which makes total sense to me.

Example:
OpenJDK 11 is located at : /usr/lib/jvm/java-11-openjdk-amd64/bin/java
OpenJDK 8 is located at : /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java
