Uninstall Oracle JRE installed from tarball

Question

I installed Oracle Java using this wikihow tutorial

This method involves removing OpenJDK, downloading a tarball, uncompressing it, and moving the binaries to system directories. This means that the application is unknown to dpkg and not found by any apt command or other package manager.

I tried the solutions in Uninstall Oracle JRE installed from tarball but they do not work for my case, for the reasons explained above.

Pretty thorough instruction over here: http://askubuntu.com/questions/84483/how-to-completely-uninstall-java — TheRoyalTnetennba, Feb 10 '17 at 02:42
Ok guys, this is not the first time I use the forum. this issue is not a duplicate. please read the problem and the way I got there. I already read all the java tagged discussion, nothing will fix my problem. Any ideas? — Bluue Squirrex, Feb 10 '17 at 18:07
Also it shouldn't be closed imo because Bluue Squirrex self-answered it. — karel, Feb 11 '17 at 08:04

sudo update-alternatives --remove "java" "/usr/local/java/jre1.8.0_121/bin/java"    
sudo update-alternatives --remove "javac" "/usr/local/java/jre1.8.0_121/bin/javac"    
sudo update-alternatives --remove "javaws" "/usr/local/java/jre1.8.0_121/bin/javaws"    
sudo rm -r /usr/local/java/jre1.8.0_121
sudo updatedb
sudo locate -b '\pack200'
sudo rm /home/pietro/Documents/java/jre1.8.0_102/bin/pack200
sudo rm /usr/share/bash-completion/completions/pack200

This is how I managed to get rid of it.
