Threads and join

I have a question about joining of threads: i have 3 threads (t1, t2 and t3). t1 can't start unless t3 has finished his job. and t2 can't start unless t1 has ended.

how do you do this in code? where do you place the instance.join() methods?

You put that code in some class that controls the action of those three threads. Like this:I suppose this must be a simplified example of your real problem, though, because it doesn't need threads at all. Just call the three bits of code designated as "..." one after the other.

no it's not a simplified version of a real world problem. i do know what the purpose of the join method is, but i don't know what it means if you call t1.join()

if you call t1.join() from the run-method of t2 will then t2 wait until t1 has finished ?
It is sorta covered in the JavaRanch Style Guide.
