How to remove Oracle JDK
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
sudo rm -r /usr/lib/jvm/jdk[version]
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
sudo update-alternatives --config javaand choose an openjdk verion. Delete the oracle jdk files and if you need to uninstall openjdk too, do it with the Ubuntu Software Center.
how about symlinks? will it become trash link? how should i do to purge remove all settings and configuration from Oracle JDK?
These links point to the chosen Java: /usr/bin/java -> /etc/alternatives/java and /usr/bin/javac -> /etc/alternatives/javac
