If you call join() on a thread, it won't return until that thread terminates. So what join() does is wait for a thread to complete.

Imagine you want to start ten worker threads, then do something when all ten are finished. You'd create the ten threads, store them in an array, the start them all. Then you use a for loop to call join() on each one. When the for loop completes, all then threads have finished their work.

the currently executing thread stops until the thread on which join() was called completes.
 
It is sorta covered in the JavaRanch Style Guide.
