Akka Actor's lifecycle example

In this section, we will develop a couple of Actors to explore Akka Actor's lifecycle methods in detail. Perform the following steps to explore Akka Actor's lifecycle:

1. Create a Scala/Akka SBT project in your favorite IDE ( I am using IntelliJ IDEA IDE):

      Project name: akka-actor-lifecycle-app

2. Add the following configuration to the sbt file:

build.sbt:

      name := "akka-actor-lifecycle-app"
      version := "1.0" 
      scalaVersion := "2.12.2" 
      libraryDependencies ++= Seq("com.typesafe.akka" %% "akka-actor" %
       "2.5.9") 

3. Create the ActorLifecycleApp file, as shown:

ActorLifecycleApp.scala:

      package com.packt.publishing.actor.lifecycle 
 
      import akka.actor.{Actor,ActorSystem,Props} 
 
      class LifecycleActor extends Actor{ 
        override def preStart(): Unit = { 
          println("LifecycleActor::preStart() invoked.") 
        } 
        override def receive: PartialFunction[Any, Unit] = { 
          case _ => 
            println...
