Question

I need to create a thread from the thread pool and need to pass a task id – a unique id that kept in my Runnable object – as the thread name.

I looked in to the ThreadFactory interface, but in that I couldn’t pass any additional parameter as thread name to the thread created. Also, I looked at the DefaultThreadFactory class. It uses an AtomicInteger to set the thread name.

Can I pass an arbitrary string to the factory and have it use that string as the name of the thread created?

You can set the name of the thread executing your task as:

class YourTask implements Runnable {
  public void run() {
    Thread.currentThread().setName(getTaskId());
    //.. rest of the code for the task
  }
}

This is probably what you want anyway. A thread that is created by the thread pool might be used for executing many different tasks – so giving the thread a name which is dependent on the task that it will eventually run is not possible.
