How to install Java?

[Newbie Comp user]

Hey guys & Hellnoire!

This is my first problem regarding Linux, how to install java to play java contents.

I was redirected here: http://www.java.com/en/download/linux_manual.jsp?locale=en&host=www.java.com:80

I downloaded the "Linux (self-extracting file)" from the link above...
From there on, I don't know how to 'install' it and yes I was aware that there were instructions on the side. However, I don't even know what they mean on the first step.

Thanks!

EDIT: I forgot to mention, I'm running Ubuntu on a Virtual Machine. Thanks again

If you're running Ubuntu,

sudo apt-get install sun-java6-jre sun-java6-plugin

and assuming you might have installed iced-tea or it was installed by default, run

sudo update-alternatives --config java

and make it point to the sun-java6-jre

I apologize that this is the only time I can thank you.
It's due to the fact that we have exams coming up (next week).
It's really kept me busy and a bit pressured about.

THANKS AGAIN!
