Examples of java.util.concurrent.ExecutorService.invokeAll()

java.util.concurrent.ExecutorService.invokeAll()
Executes the given tasks, returning a list of Futures holding their status and results when all complete. {@link Future#isDone} is {@code true} for eachelement of the returned list. Note that a completed task could have terminated either normally or by throwing an exception. The results of this method are undefined if the given collection is modified while this operation is in progress. @param tasks the collection of tasks @param < T> the type of the values returned from the tasks @return a list of Futures representing the tasks, in the samesequential order as produced by the iterator for the given task list, each of which has completed @throws InterruptedException if interrupted while waiting, inwhich case unfinished tasks are cancelled @throws NullPointerException if tasks or any of its elements are {@code null} @throws RejectedExecutionException if any task cannot bescheduled for execution
