Akka Props

Props is a configuration class which is used to specify options while creating an actor. It is immutable, so it is thread-safe and shareable.

You can implement Props by importing akka.actor.Props package.

You can create actor by passing a Props instance into the actorOf() factory method which is available in ActorSystem and ActorContext. The actorOf() method returns an instance of ActorRef. This instance is immutable and has one to one relationship with the actor it represents. ActorRef is also serializable so that you can serialize it.

In the following example, we are creating an Actor by using Props.
