Languages do not age the way that people think they do.
COBOL and BASIC are alive and well.
C will never go away.
For writing simple filter programs, it is a very good alterative.
Languages like C# and Java have to go garbage collection and hence are
unsuitable for real-time stuff.
Can you imagine .NET installed on a toaster IC to pop your toast up in the
morning? I can't.


Java is used extensively on embedded devices. You're making yourself
look a bit silly, there.

How does your response relate to my post?

Is Java used for real-time systems (if so, they should fire the product implementors for incompetence).

Does Java require .NET?

I think you have a reading comprehension problem.



You were lumping Java and .NET together, suggesting that they were
inadequate in real-time systems for the same reason. I assumed you
must have been talking about embedded stuff as well because of your
vague reasoning and toaster example*. In other words, you seemed
confused. I made a logical leap as required.

Go on then - I would like to know how garbage collection affects
real-time systems. A good reason, showing thought and reason. In other
words, show us that you're not just full of ***.

Bear in mind that garbage collection shouldn't affect the behaviour of
a system, only its constraints.

* Exactly how precise do you think a toaster timer needs to be?
How precise does a feedback loop in control
need to be,when the loop goes round 1000
times per second? Even malloc/free can be
to much there.
With LISP as an example, calculating a fractal,
it stopped every 2 seconds,to do garbage collection
for 1 or two seconds.
Things just depend on how real time your
program is,and hoe short your time tick is.
If short enough,any housekeeping job can be to much,
in which case I am glad to have an old
C compiler,without those nice new features.
