I didn't find any related articles about How to remove Oracle JDK. There are some related articles but they didn't solve the problem.
I installed Oracle JDK tarball file from Oracle site by following this article How do I install Oracle Java JDK 7. It was very helpful. But still I don't know what I should do in order to uninstall Oracle JDK.
It could be done like this:
Remove the link:
sudo update-alternatives --remove "java" "/usr/lib/jvm/jdk[version]/bin/java"
sudo update-alternatives --remove "javac" "/usr/lib/jvm/jdk[version]/bin/javac"
sudo update-alternatives --remove "javaws" "/usr/lib/jvm/jdk[version]/bin/javaws"
Then, remove the package in the /usr/lib/jvm:
sudo rm -r /usr/lib/jvm/jdk[version]
Note :
Change [version] with any version number that's contained in jdk
folder's name, example: jdk[version] = jdk1.7.0_13.
If you are new to Linux, you should probably get familiar with the manual page. Lot of good stuff from there. Just go to the terminal and type
man update-alternatives.
