Scala - ScheduledFuture

Question

I am trying to implement scheduled future in Scala. I would like it to wait specific time and then execute the body. So far I tried the following, simple approach

Answer 1

If you want schedule the completion without Akka, you can use a regular Java Timer to schedule a promise to complete:

def delay[T](delay: Long)(block: => T): Future[T] = {
  val promise = Promise[T]()
  val t = new Timer()
  t.schedule(new TimerTask {
    override def run(): Unit = {
      promise.complete(Try(block))
    }
  }, delay)
  promise.future
}
