Other Parts of This Series: Part 4: Reactive Programming in Java - Part 4 (Other Useful Operators) Reactive Programming (Photo Credit: zibtek.com) In the previous parts we were trying to learn everything need to start the reactive programming. In this part we will try to explore how to handle error in Reactor. So, let’s start… Error Handling Operators onError Callback: Suppose we need to do something when an error occurs by catching it from the try…catch block. The ideal case in regular programming is something that looks like the example below: ...

Also, we introduced with project Reactor and some of most important operators, what are marble diagrams of operators, and how can we start thinking in a reactive way? In this part we will try to explore other useful operators. So, let’s start… ...

Other Parts of This Series: Part 2: Reactive Programming in Java - Part 2 (Thinking In Reactive Way and Reative Operator) Reactive Programming (Photo Credit: Reactive Programming Book by Sergi Mansilla) Before deep dive into hands on reactive programming using Java, let’s understand the core concepts first. What is Reactive Programming? In simple words, as its name suggests, reactive programming is a kind of programming paradigm that can react based on something. It uses declarative code (in a manner that is similar to functional programming) in order to build asynchronous processing pipelines. It is an event-based model where data is pushed to the consumer as it becomes available: we deal with asynchronous sequences of events. So reactive programming is programming with asynchronous data streams. ...
