wait() and notify() methods.
Begin by creating five philosophers,
each identified by a number 0 ... 4.
Each philospher runs in a separate thread. Philosphers will
alternate between thinking and eating.
When a philosopher
wishes to eat, it invokes the
method takeForks(philNumber),
where philNumber identifies the number of the
philosopher
wishing to eat.
When a philosopher finishes
eating, it invokes
returnForks(philNumber).
Your solution will implement the following interface:
public interface DiningCoordinator
{
// called by a philosopher when it wants to eat
public void TakeForks(int philNumber);
// called by a philosopher when it is finished eating
public void returnForks(int philNumber);
}
The implementation of the interface follows the outline of
the solution referred to
above.
Implement using the keyword synchronized,
along with wait(), notify(), and notifyAll().
To get more
interesting behavior, use a helper class
so your philosophers can take naps.
Big questions:
shold you use notify() or notifyAll()?
Should you test conditions using while-statements
or if-statements?
