Examples of java.util.concurrent.ThreadFactory.newThread()

java.util.concurrent.ThreadFactory.newThread()
Constructs a new {@code Thread}. Implementations may also initialize priority, name, daemon status, {@code ThreadGroup}, etc. @param r a runnable to be executed by new thread instance @return constructed thread, or {@code null} if the request tocreate a thread is rejected
