Re: FutureTask.cancel() - can anyone explain the mechanism?

         public Integer call() {

            try {

                while(true) {
                    final String message = this.blockingQueue.take();
                    System.out.println(message);
                }
            }
            catch (Throwable t) {
                System.out.println("Throwable caught in call() " + t.getCause
().getMessage());

             }
            finally {
                System.out.println("Entered call() finally block.");
            }

            return new Integer((int)0);
        }
    }

    public static void main(String[] args) {

        final ExecutorService executor = Executors.newSingleThreadExecutor
();

        final MyCallable myCallable = new MyCallable();

        final Future<?> myFuture = executor.submit(myCallable);

        myCallable.put("Go Southend United FC!");

        myFuture.cancel(true);
