this sounds like a job for a concurrent construct called a barrier.
a barrier serves as a rendezvous point for some number of threads.
doug lea has an implementation of barriers in his "concurrent"
package; visit

for more info.
alternatively, and less elegantly (or maybe if you don't control
the nature of the threads), you could just do successive join()s
on the three threads you launch. ugh. 8^)
