This is part 2 of the series called “Functional Java by Example”.
The example I’m evolving in each part of the series is some kind of “feed handler” which processes documents. In previous part I started with some original code and applied some refactorings to describe “what” instead of “how”.
In order to help the code going forward, we need to tell a story first. That’s where this part comes in.

Functional Programming (FP) is about avoiding reassigning variables, avoiding mutable data structures, avoiding state and favoring functions all-the-way. What can we learn from FP if we would apply functional techniques to our everyday Java code?
In this series called “Functional Java by Example” I will refactor in 8 installments an existing piece of code to see if I can reach Functional Nirvana in Java.
