In the video below, we take a closer look at the what observers and observables are in Java, with eof each. Let's get started!
Observer and Observable in Java [Video]
Observer Pattern in .NET
Introduction
I have previously written a few posts about delegates, .NET Events, Events Args to show that similar to real-world events, we can use this concept in our code and how useful they are in certain scenarios. This post will see that those types are a good candidate for implementing the observer pattern without doing anything extra. We will learn some terminologies and see a working example as well.
If you are new to .NET Events, I will suggest reading my previous posts on the topic, and then discussed in this post will be easier to follow. So let's talk about observer pattern:
Introduction to Reactive Programming
Reactive programming is about dealing with data streams and the propagation of change.
Reactive systems are applications whose architectural approach make them responsive, resilient, elastic and message-driven.
