Scala combines two programming paradigms: object oriented and functional. As a result you get best from the two worlds. From the one side you can describe models as objects, from the other side you can apply functions to them. And as you may guess, it's really awesome! Let's discover today basics of Scala functions.
How a newcomer can understand Akka's principles of work? Couple of examples from the documentation could be not enough. From the other side, a simple application which shows Akka in action is a very good way for demonstration of Actors capabilities. So let's start the acquaintance with the simple Akka use case!
How we can build a close interaction between Actors? Just with help of messaging. In the previous post I've already demonstrated how we can send messages between Actors. In this post I want to continue topic of message exchange, but this time let's develop cooperation of two Actors which interact with each other.
Probably the most popular process which happens behind the scenes in Akka is a messaging. And it's not, what comes to mind instantly, no any text messages like in Skype or mobile phones. Akka Actors can deal with different objects and classes which represent messages (Strings also allowed). As usually I'll use Scala as a programming language.
