How much are SOLID principles in OOP programming (and JVM languages specifically) just a mindless following of a set of ideas that aren't always the best solution? (programming.dev)

As a Java engineer in the web development industry for several years now, having heard multiple times that X is good because of SOLID principles or Y is bad because it breaks SOLID principles, and having to memorize the "good" ways to do everything before an interview etc, I find it harder and harder to do when I really start to dive into the real reason I'm doing something in a particular way.

One example is creating an interface for every goddamn class I make because of "loose coupling" when in reality none of these classes are ever going to have an alternative implementation.

Also the more I get into languages like Rust, the more these doubts are increasing and leading me to believe that most of it is just dogma that has gone far beyond its initial motivations and goals and is now just a mindless OOP circlejerk.

There are definitely occasions when these principles do make sense, especially in an OOP environment, and they can also make some design patterns really satisfying and easy.

What are your opinions on this?

I guess it's possible I've been doing OOP wrong for the past 30 years, knowing someone like you has experienced code bases that uphold that promise.

Right, knowing when to apply the principles is the thing that comes with experience.

If you’ve literally never seen the benefits of abstraction doing OOP for thirty years, I’m not sure what to tell you. Maybe you’ve just been implementing boilerplate on short-term projects.

I’ve definitely seen lots of benefits from some of the SOLID principles over the same time period, but I was using what I needed when I needed it, not implementing enterprise boilerplate blindly.

I admit this is harder with Java because the “EE” comes with it but no one is forcing you to make sure your DataAccessObject inherits from a class that follows a defined interface.

We all have or own experiences.

Mine is that it helps in organization, which makes changes easier.
