## Interface ThreadFactory

-     public interface ThreadFactory

  An object that creates new threads on demand. Using thread factories removes hardwiring of calls to `new Thread`, enabling applications to use special thread subclasses, priorities, etc.

  The simplest implementation of this interface is just:

       class SimpleThreadFactory implements ThreadFactory {
         public Thread newThread(Runnable r) {
           return new Thread(r);
         }
       }

  The `Executors.defaultThreadFactory()` method provides a more useful simple implementation, that sets the created thread context to known values before returning it.
