It's "where java" on windows, and I think whereis on *nix.

If you mean programatically, just access the class/sdk component or 
other service.  If you get an exception, it wasn't installed.  Some 
programs (like ant) require you to set the JAVA_HOME environment 
variable to identify which SDK you want to use (some users have more 
than one).  I prefer using command line arguments or cofig files; 
polluting the environment with lots of tedious variables is a last resort.
