Yes the better solution is to make more JDK versions by using "update-alternatives" command.

After that you can also set PATH using the command.

export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_11 or /usr/lib/jvm/jdk1.6.0_38 export PATH=$JAVA_HOME/bin:$PATH

If you want to remove completely that java version you need to remove the packages that contain it, see a list of packages with:

sudo dpkg --get-selections | grep jre

In this way you see what jre packages you've installed. Then you can remove the packages with:

sudo apt-get remove old_jre_package

Anyway a better solution is to make more JDK versions coesist, in Ubuntu is easy to do it. You can use the update-alternatives command. So you can install another JDK and switch between the jdk versions with the alternative tools:

sudo update-alternatives --config java
sudo update-alternatives --config javac

For more options see the man page man update-alternatives.

You can search all the jre package in your system by running this command

sudo aptitude search jre

Remove it using this command 

sudo apt-get remove sun-java6-jre sun-java6-plugin sun-java6-fonts

You can also try this command to remove all the java files in your system 

sudo aptitude remove '~njava'
