Executors from the java.util.concurrent package are the way to go. Explicitly:

ExecutorService executorService = Executors.newCachedThreadPool(new ThreadFactory() {
     @Override
     public Thread newThread(Runnable runnable) {
          Thread thread = Executors.defaultThreadFactory().newThread(runnable);
          thread.setDaemon(true);
          return thread;
    }
});

Java 8 version with fixed ScheduledExecutorService

ScheduledExecutorService executorService = Executors.newScheduledThreadPool(1, r -> {
    Thread thread = Executors.defaultThreadFactory().newThread(r);
    thread.setDaemon(true);
    return thread;
});
