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).


There is a real time Java specification, and Sun has released a real
time version of Java (RTS). A high-level introduction is at
http://www.onjava.com/pub/a/onjava/2006/05/10/real-time-java-introduction.html?page=1.

"Real-time Java offers a much more reliable and predictable scheduling
mechanism, memory handling methods, different memory models, a more
predictable threading and synchronization model, asynchronous event
handling, and high-resolution time handling. It makes predictable
execution the first priority in all trade-off decisions, sometimes at
the expense of typical general-purpose computing performance measures.
This is what real-time means."
