Executor Service - timeout of thread

Question

While I was exploring ExecutorService, I encountered a method Future.get() which accepts the timeout.

The Java doc of this method

Answer 1

my callable will interrupt after the specified time(timeout) has passed

Not true. The task will continue to execute, instead you will have a null string after the timeout.

If you want to cancel it:

  timeout.cancel(true) //Timeout timeout = new Timeout();

P.S. As you have it right now this interrupt will have no effect what so ever. You are not checking it in any way.

For example this code takes into account interrupts:

    private static final class MyCallable implements Callable{

    @Override
    public String call() throws Exception {
        StringBuilder builder = new StringBuilder();
        try{
            for(int i=0;i

And then:

        ExecutorService service = Executors.newFixedThreadPool(1);
    MyCallable myCallable = new MyCallable();
    Future futureResult = service.submit(myCallable);
    String result = null;
    try{
        result = futureResult.get(1000, TimeUnit.MILLISECONDS);
    }catch(TimeoutException e){
        System.out.println("No response after one second");
        futureResult.cancel(true);
    }
    service.shutdown();
