How do I implement task prioritization using an ExecutorService in Java 5?

Question

I am implementing a thread pooling mechanism in which I\'d like to execute tasks of varying priorities. I\'d like to have a nice mechanism whereby I can submit a high prior

Answer 1

Would it be possible to have one ThreadPoolExecutor for each level of priority? A ThreadPoolExecutor can be instanciated with a ThreadFactory and you could have your own implementation of a ThreadFactory to set the different priority levels.

 class MaxPriorityThreadFactory implements ThreadFactory {
     public Thread newThread(Runnable r) {
         Thread thread = new Thread(r);
         thread.setPriority(Thread.MAX_PRIORITY);
     }
 }
