multiple waiting threads. only one notified

[duck worth]

Hi all,

Easy-peasy one for somebody. You have multiple threads calling waiting for another thread. But that thread only calls notify(). Hence only tells one of the waiting threads the lock is going to become available. What happens to the other poor threads. Do they wait forever more???

They'll wait until notify is called again. Or notifyAll is called.

so basically, if the thread never calls it again they're stuck. Suppose that leaves it down to sensible code design

many thanks

Yes, they are stuck.

But the wait method is overloaded to take a long value that specifies the time limit in milliseconds. if this is exceeded, it simply carries on.
