For years, we've relied on design patterns to guide us to solutions that are clean, simple and practical, but many of the classic OO design patterns laid out in the Gang of Four's book are actually workarounds for the lack of functional programming constructs such as lambdas and higher-order functions. With new tools at our disposal, we can simplify the majority of design patterns, using pure functions to reduce the proliferation of classes that are used once and thrown away. By removing the boilerplate surrounding our code, we focus on the most important part: the behaviour.
In this talk, Samir Talwar will lead you through the classic design patterns, as well as some more contemporary object-oriented principles, showing you how functions can drastically simplify your design, leading to code that is cleaner and more concise.
This presentation will cover a few design patterns, but the focus is on Java 8. It's a slideshow, so it's not live coding, but practically all of the slides are entirely code, so you should be comfortable reading it.
