Functional Java by Example | Part 8 – More Pure Functions

This is part 8, the last instalment 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 the last instalment we’ve seen some pattern matching, using the Vavr library, and treated failures as data too, e.g. take an alternative path and return back to the functional flow.

In this last post of the series I’m taking functions to the extreme: everything becomes a function.
