This is second post in a series of “Actors using Scala & Akka”. In Part 1, we saw how to create new actors and modify their state by sending messages.
In this articles we will take a look at how to get a reply from actors (i.e.Ask Pattern) and spawning user actors (Spawn protocol) instead of system actors.
Since I am stuck at home due to Covid-19 pandemic. With nothing else to do, I thought the best use of time would be to continue my blog series about actors. In the last article, we saw what are actors, their properties and how these properties can be useful for writing concurrent and stateful applications. It was all theory. In this article, I will demonstrate how to write your first akka actor in scala using IntelliJ IDE. Hop on even if you don’t know scala.
The actor model of computing was introduced by Carl Hewitt in 1973. This model makes it easy to tackle the problem of concurrency and state management. The model treats an “actor” as a primitive unit of computing.
