ExecutorService with 1 thread

[Jim Bob]

Hi There,

Can someone answer me this question: If I create an ExecutorService like so:

ExecutorService myService = Executors.newFixedThreadPool(1);

and then call(pseudocode):

myService.submit(sometask1);
myService.submit(sometask2);

Is it guaranteed that seeing as the ExecutorService only has one thread (see constructor above), is it guaranteed that sometask2 will only execute after sometask1 has finished?

In other words, with a pool size of 1, sometask1 and sometask2 will never execute concurrently in this situation??

thanks a lot.

Please re-read the section on 'obviously fictitious names' and change your name appropriately.

The Executor interface JavaDoc includes a sample Executor that runs one task at a time, if that's your objective.
