java is NOT the application.  It is the language and runtime for the
application.  If an application wants to use multiple CPUs, then the
author of the application should write a threaded application.

There is certainly research into making runtimes and languages that
can automatically make some parts of the code run in parallel, but that
isn't something you are likely to see in current production systems.

So if your application written in java creates multiple threads, then
it will use multiple CPUs just fine.
