Get running and queued tasks from ThreadPoolExecutor?

Question

I need to display all running tasks to the user. Every task is associated with a specific id. To execute tasks I use a ThreadPoolExecutor. Each thread has the same name as the id. So I just have to get list of all running and and waiting in queue threads. And then get there names and display them.

How can I do this?

Answer 1

Subclass the executor, override execute, beforeExecute and afterExecute to keep an administration of the scheduled and running tasks.
