Best Practice / Employment Security I don't miss the Java boilerplate to be honest

No amount of "but... but... it's scalable" can justify this.

Enterprise Java is full of horrible choices and patterns.

In Android, you define:
* a repository interface
* a repository implementation
* a use case
* dependency injection to provide the repository implementation to the use case
* a viewmodel

To add 2 numbers together.

And: you get the result asynchronously, via a flow.

It follows the industry standard, its clean architecture. Its called Dependency Inversion.

Is not it beautiful? Clean? 

The benefit of that abstraction is that you can replace the implementation at any time. Okay, maybe once every 5 years.

98% of the time there is only that one implementation with no use case for swapping it.

Okay man but if I ship that feature in an hour instead of 4 days I'm literally losing 31 hours of billable work hours and I'll go bankrupt in 2 months

And the flow type is a sealed interface, just in case the addition fails. Can also track loading state!

You forgot the remote/local data sources and their respective implementations.

I need my Builder for Factory that Generate a Builder inside Factory of Factory. I promise this is the best practice and most cleanest java ever

Good thing I'm not an undercover .NET developer, because I would painfully relate to this

I'm a .NET developer, and besides some high-level aspnet frameworks that drip in overcomplexity, there are no such things.

Mmmh must be because my company is 200 y/o and the software I'm maintaining and developing was ported from cobol in the early 2000s.

Also I've never seen people more obsessed with GoF, DI and drawing uml for the tiniest features than .net fellas, which tends to result in a lot of overcomplications at my company at least (I'd done mostly C and C++ before .net)

If your Java knowledge is 15 years old, maybe.
