How to create an Akka ActorSystem?

ActorSystem has one class and one object, as shown here:

object ActorSystem{ } 
abstract class ActorSystem{ }

We can create an ActorSystem using one of its overload create() functions, as shown here:

val actorSystem1 = ActorSystem.create("FirstActorSystem")
println(actorSystem1) 

When we call the ActorSystem.create() method, it internally calls its available  apply() methods, so we can simply use the following code to create an ActorSystem:

val actorSystem2 = ActorSystem("SecondActorSystem")
println(actorSystem2) 

In both of these examples, we are giving a name to the ActorSystem. If we don't provide a name, Akka will assign a default name. Consider the following example:

import akka.actor.ActorSystem object ...
