How do you cancel a scheduled Thread in an ExecutorService?

Executors in the Middle Ages
Humm... I thought...

I was asked this question a while ago, and I came up with a quick solution since it was just a general question. I went back and cleaned up my example which uses Callable and Future to demonstrate the concurrency libraries in Java.

In the example, I use a ExecutorService with a fixed thread pool size of two (2), to make the code slower to demonstrate the point. You can manipulate the value to see the effect on the code execution.

The code is to demonstrate you can do it,  there may be other cleaner ways of doing this. If you have an example, or idea on how to do it cleaner, please comment. :-)


The code for the project was developed using NetBeans and can be downloaded from Bitbucket at the link below. It is a NetBeans (Apache Ant) based project and should work with Ant without NetBeans.
