There is NetBeans package in Ubuntu repositories. The official and supported way is to install it using apt. In that case, NetBeans will be updated automatically.
Problem with this approach is that current NetBeans package is not the last one. On November 23rd 2008 it was version 6.01. In case that you need newer package, follow procedure described in Installing NetBeans 6.5 on Linux / Ubuntu.
Checking Current Version in Repository
Current version in repositores can be obtained by:
apt-cache show netbeans
This is the result of execution of the command above:
