Nothing to configure.

/etc/alternatives/java -> /opt/java-oracle/jdk1.8.0/bin/java

sudo update-alternatives --config javac

fwiw, I was looking for the oracle jdk, which can be found here: http://www.webupd8.org/2012/09/install-oracle-java-8-in-ubuntu-via-ppa.html — user7134, Nov 11 '14 at 19:27
https://askubuntu.com/questions/48468/how-do-i-install-java/1051470#1051470 is probably the more useful question (it actually gives a number of solutions) — Thomas Ward, Jul 03 '18 at 13:44

I installed the jdk just fine. Here's what I did.

Get the .rpm file from Oracle's website.
Open up a terminal and type this command:sudo apt-get install alien
Wait for alien to install.
Type: sudo alien -i -c <path to the file>
Wait for that to finish installing. It will look like it's not doing anything for a while, but it is.
Test the installation with: java -version
You're done!

I followed the suggested steps today, but was upset by the result. Mostly because installed Java was not registered in java-alternatives among other versions, and also because of apt complaining about "1 not fully installed or removed."

So I decided to provide an alternative answer.

The following steps made me happy today:

Get the .tar.gz file from Oracle's website
Use the following command to install the package converter specific to Java: sudo apt install java-package
In the directory containing previously downloaded file, run the command: make-jpkg jdk-8u221-linux-x64.tar.gz (adjust the version if needed).
Then run: sudo dpkg -i oracle-java8-jdk_8u221_amd64.deb (adjust the version if needed).
If you have any other versions of Java installed, you may need to update alternatives: sudo update-java-alternatives --set oracle-java8-jdk-amd64
Check everything is OK: java -version.

Now you can delete both .tar.gz and .deb files.
