  • There is a difference the way both methods handle Exception. If your tasks throws an exception and if it was submitted with execute(Runnable) this exception will go to the uncaught exception handler.
  • If you submitted the task with submit(Callable) any thrown exception, checked exception or not, is then part of the task’s return status.
  • For a task that was submitted with submit(Callable) and that terminates with an exception, theget() will re-throw this exception, wrapped in an ExecutionException.
