Question

I have an application which creates a new thread on a socket connection. I would like to submit a Callable from this thread to an ExecutorService. The Callable needs to execute a program via a command line argument, so I don’t want to do this via the connection thread.

The problem is, I don’t know how to submit the Callable to an ExecutorService which has a set thread count.

I had considered doing this with a singleton and writing a submit method to submit my Callable to the ExecutorService instance but being unfamiliar with the api, I wasn’t sure if this was sensible.

Any help is greatly appreciated,
Thanks.

Answer 1

I would try

 static final ExecutorService service = Executors.newFixedThreadPool(4);

 Callable call = 
 service.submit(call);
