You'll have to define what you mean by "Real-Time Systems". I know lots
of people who think that a workstation based application which has to
respond to user's mouse-clicks in some acceptable amount of time is
"Real-Time". Then you've got systems that have to monitor and adjust
some real world electromechanical contraption where response time has to
be measured in milliseconds - or even microseconds - and stopping to
collect the garbage is just not an acceptable thing to do.
Java can be used for real-time if you are very careful about what you
call real-time. But that's like saying that Unix is "user-friendly" only
its very picky about who its friends are.
