Loops and timing in Java...

[rjlohan]

It's been awhile since I used Java, and I don't think I've got a compilet to test this for myself...

Say I have a set of objects (all derived from the same class) and I need each object to check for some condition every 1 second say, how would I construct this in Java? Can each object run an independant loop, or not, as I guess is the case?
Would I instead need one major loop to go through and make each object check the condition?

Yes, you can do this. Check out threads.

Ok, that's good enough for me. I only need to know it to build a design spec for a system (uni project...).
I don't actually have to code it, so that's great.
Cheers.

Without getting into threads in the context
of spawning i would just use the
public static void sleep(long millis)
methods that are defined in the
java.lang.Thread class.

// process at one second intervals
for(Iterator i = v.iterator(); i.hasNext();){
  processObject(i.next());
   Thread.sleep(1000); 
}

Sorry, that was a bit over my head.
I've just got a major project at uni this semester, and I've got to design a control system for an elevator. Fun stuff...

I don't actually have to code it, just do specs and requirements and stuff, so I just needed an overview, and info on whether Java had multithreading capabilities, which I guess it does, so that's good enough.

Cheers, all.
