Using the guide here: I have installed Oracle's JDK because it has a few features that are not present in OpenJDK.

Now, there some new features released in the Early Access of Oracle's JDK which I need.

I have two questions pertaining to this:

  1. How do I completely get rid of Oracle's JDK ?

  2. How do I upgrade my current Oracle JDK ?
    Given that my knowledge is limited to the guide, I guess the changes will be after step 9 where I will have to replace jdk1.7.0_40 with the appropriate version.

Please help me with this =)

You can just download a new version, untar it into /usr/lib/java/ near the old java version and update symlinks by "sudo update-alternatives" like in your tutorial. And don't forget to change env varible JAVA_HOME to new java directory (/usr/lib/java/< new_version >).
