Source Code structure

[Genzer]

I want to evaluate the test some approaches to organize source code. Preferably language agnostic, but Java just fine.

Principles:

• Package by features
• Isolation of modules

Architecture Styles:

• Clean Architecture
• Hexagonal Architecture
• Onion Architecture
• something else
