Java is an old evil and a lot of people do not like her, as you know, however, sometimes it comes in handy 😉
Personally, I use it to install dedicated servers using IPIMI.

Below, a simple guide on how to install it on deskopowych versions of Ubuntu and Linux Mint.

Open a terminal as root and add to the repository system:

sudo add-apt-repository ppa:webupd8team/java

We then upgrade packages package and charge the selected version:

sudo apt update; sudo apt install oracle-java8-installer

If you would like to install a version 9 just change the version number:

sudo apt update; sudo apt install oracle-java9-installer

We reaffirm the terms of the license and continue.

We check to see if everything was OK with the command:

javac -version

Should we show version in our system.

Then you are installing Java as the default for your system:

sudo apt install oracle-java8-set-default

for java 9 similarly:

sudo apt install oracle-java9-set-default

It's all java is installed and can manage the menu system.
In the case of java9 it has a little better compared to the gui version 8.
