My Ubuntu 10.04 already had Eclipse 3.5 along with Android stuff. I downloaded a new version Eclipse 3.6 Helios Java EE for Ubuntu and unzipped it. So how can I get Eclipse 3.6 running when I type eclipse at terminal or click on the menu (Applications -> Programming -> Eclipse)

It seem to Eclipse 3.6 is not add to the Ubuntu repository yet.

What is the location of Eclipse 3.5 on my Ubuntu 10.04?
