Why I love everything you hate about Java

I find it odd that while the article is titled about Java, all of the code examples are in Scala. The statement "function composition is a degenerate case of the Decorator pattern" in the blog is bizarre to me. OO languages like Java have to resort to the Decorator pattern to handle their lack of composibility; that seems far more degenerate than a language that supports this kind of composition without hacks. Also this article is 2.5 years old.

Um, I don't hate Factories, Dependency Injection and Decorators. I hate that Java makes it very cumbersome to use them, typically via xml configuration files (so that it can be dynamic) and adding complex syntax (generics, annotations). And I hate that I can not pass functions as parameters. As he says in the article: "function composition is a degenerate case of the Decorator pattern." (not sure why "degenerate") - so instead of just composing functions, in Java I have to…

Avdi Grimm responded [0] to this (relatively old) article with what I think is a salient point: traditional design patterns are good, but Java makes expressing these design patterns very obtuse and heavy-handed. Nick Kallen conflates using intelligent design patterns with calling out every use of said design patterns in bold-face. Writing Java feels like "now I'm going to make a Factory Factory! See, it says FactoryFactory right there in the class name!" It's entirely natural to use intelligent design…
