Hi, In theory I understand the way Threads join() method works, but when I am testing it with some code, I am getting unexpected results. I thought if you say: 1. start a thread1 2. start a thread2 3 do thread2.join() I thought the result would be thread1 will pause until thread2 finishes then go back to runnable and eventually finish. Here's my code with an exlanation of results:
No matter how I change the for loop counter int in run(), Fred always finishes before Lucy. Surely he has joined the end of Lucy and must wait till she finishes. Thanx for any help

What you have stated about the join() method is exactly right. The analysis of your code can be done as follows: There are 3 threads running namely, 1>mainthread 2>Fred thread 3>Lucy thread The code starts the threads "Fred" and "Lucy" in the "main" thread. Therefore,we call the join() method on the "main" thread and not on the thread named "Fred".Hence there is nothing you can do with the run() method.
