This is part 7 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. We’ve already dealt with exceptional situations before, but we’re going to take care of them, more ehm,…functionally — as data.
This is part 6 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 we tried to make our functions as pure possible by moving as much of the side-effects, such as IO, to the outside of the system. Now … Lees verder Functional Java by Example | Part 6 – Functions as Parameters
This is part 5 of the series called “Functional Java by Example”. In previous part we stopped mutating our documents and returned copies of the data. Now, we need to move some I/O away.
This is part 4 of the series called “Functional Java by Example”. In previous part we talked a bit about side effects and I’d like to elaborate a bit more about how we can prevent having our data manipulated in unexpected ways by introducing immutability into our code.
This is part 3 of the series called “Functional Java by Example” and is a cross-post from my personal blog. The example I’m evolving in each part of the series is some kind of “feed handler” which processes documents. In previous parts I started with some original code and applied some refactorings to describe “what” instead of “how”. In order … Lees verder Functional Java by Example | Part 3 – Don’t Use Exceptions to Control Flow
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 … Lees verder Functional Java by Example | Part 2 – Tell a Story
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 … Lees verder Functional Java by Example | Part 1 – From Imperative to Declarative
