thanks , thats great .:) i though the only way to terminate a thread is to
use interrupts and an un-handled exception generated by sleep() :)
 by the way it is the source code whith my latest knowledge . it now
compiles fine thanks to you guys , kills a thread , and then specifically i
can manage each thread i want . but there is a problem , the first thread
doesnt print anything on the cosole ! while the others do! i even used
mutex , but seems its not the case  . any idea?
