public interface: ThreadFactory [javadoc | source]

All Known Implementing Classes:
    DaemonThreadFactory, DefaultThreadFactory, PrivilegedThreadFactory

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.

Method from java.util.concurrent.ThreadFactory Detail:
 public Thread newThread(Runnable r)
    Constructs a new {@code Thread}. Implementations may also initialize priority, name, daemon status, {@code ThreadGroup}, etc.
