Hi SpoonsJTD,
I do not understand your question. Actionscript runs on desktops, too and in future Shockwave will be written in an EMCA Language, too (very likely AS but thats just gossip).
Java is used as a web technology, too and yeah, it runs on Windows, also.
To be precise Actionscript is the language with which Flash files can scripted/programmed. Maybe you add some graphics and compile the whole thing. Et voilĂ : you have a Flash movie (swf) which can be embedded almost everywhere or you create a projector (an executable).
More info on Flash here:

Actionscript is OO so using a modler makes sense, don't you think?
Regards
Olaf
