Hi all, hi again

I'm still on my thread things and i wanted to thread.quit() and thread.start() in a loop but i got this :

java.lang.IllegalThreadStateException

I looked it up on the internet and i found out we can't call start() more than one time in a program.
So here is my question :  Is there a way to restart a thread?

I've been thinking on a solution :

Thread_FIA cycle  = new Thread_FIA(); can i delete this object and create a new one at the same location in memory? cause i dont want to create several objects without freeing memory space.

Thank you
