I download and install
Java 2 Platform, Standard Edition and it cann't compile. The javac command seems non-existant (and if Sun is so 'cross-platform' as they say they will use the same commands in the compilers of all the OSs they support).
Maybe I will try NetBeans, but I have broadband only in College... it will take a while.
I'm not desperate, but I think that for now I will have to install that toy OS used in 90% of all computers and use the "standard compilers" for my first Java assignments
