it is the same javac , java tends to be platform independent unless you are using system calls that are not available on the current platform
Everything is true unless there is no java installed on your linux box, gcc-java claims to compile java programs with gcc - I've never used it though

There are some environment variables to be set first.

Have a look at what cubed says here and do this for the JDK and JRE packages.

You must logout from your account and log back in (for the .bash_profile to rerun.

The simplest way to test if java is running is:

java --version

PS. I really recommend Emacs in Java mode. It's a great IDE and won't hog memory like Suns Forte.

You don't need to logout and log back in, you can run
source .bash_profile
or
. .bash_profile
to re-read and set new environment
