java - How can I know if a task submitted to executor threw exception? -

if run thread in executorservice there way know thread did not throw exception when started execution?

as per the javadoc, can submit runnable the executor using submit()

    executorservice service = executors.newsinglethreadexecutor();     future f = service.submit(new runnable() {         @override         public void run() {             throw new runtimeexception("i failed no reason");         }     });     try {         f.get();                 } catch (executionexception ee) {         system.out.println("execution failed " + ee.getmessage());     } catch (interruptedexception ie) {         system.out.println("execution failed " + ie.getmessage());     } 

this method work when exceptions unchecked. if have checked exceptions, rethrow them wrapped in runtimeexception or use teh callable instead of runnable interface.
