Installation of third party software under Debian

[Shawn Garbett]

I've just downloaded IBM's java for linux, Star Office and VmWare. Three 
tools I use regularly while doing my work. Not that I choose these, they 
just fit with  the  group I work with and I make a living with them.

How do I install them in Debian? I noticed a package that was an IBM 
Java installer.  Is it usable with a downloaded gz file?
