linking concurrent threads

[Michael Ku]

I am working on some legacy code that spins off several threads and waits until they all finish or exceed a time limit before proceeding forward. IT is written in Java 1.2 style syncing on an object etc.

Is there any easier way to do this, say using an Executor or ExecutorService? I have reviewed these classes but I cannot figure out how to accomplish the same thing.

Thank you

this might be of some help?

I reviewed the doc at the link but I do not understand how to use it in my case. Would you please elaborate.

Does anyone else know how to do this with the ExecutorService?

With ExecutorService, you can just use the invokeAll() method - the one with three parameters, which allows you to specify a timeout. The method won't return until each task either completes or times out.
