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: ...

Other Parts of This Series: Part 3: Reactive Programming in Java - Part 3 (Introduction of Project Reactor and Some Frequently Used Operators) Part 5: Reactive Programming in Java - Part 5 (Error Handling in Reactor and Conclusion) Reactive Programming (Photo Credit: Reactive Programming Book by Sergi Mansilla) In the previous parts we were trying to understand what actually reactive programming is and how its mechanism operates. 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… ...
