FutureTalker Listeners for java.util.concurrent Java V5.0 (or V1.5 as it otherwise know) incorporates Doug Lee's Concurrent package as java.util.concurrent. This package provides many of the utilities needed for writing multi-threaded programs in Java. One notable omission is a built-in means to listen for the completion of a task.
