JREs from different vendors on the same system
You can install multiple JRE/JDK at a time. You just need to configure which one to use by using update-alternatives
sudo update-alternatives --config java
There are 2 choices for the alternative java (providing /usr/bin/java).
Selection Path Priority Status
0 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 auto mode
1 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 manual mode
* 2 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1051 manual mode
Press enter to keep the current choice[*], or type selection number: 1
Similarly, you can configure your JDK with
sudo update-alternatives --config javac

In various tutorials, it is said, that you should remove existing JRE/JDK before installing new one (e.g. remove OpenJDK before installing the one from Oracle). Is it really necessary? I remember having 2 JREs at one point, being able to choose in my IDE which to run program on.
Don't remember to have any conflicts, what's the chance of having any?
