Architecture overview

This repository represents a single modular system split into multiple JPMS modules:

• app-api-publica
  Defines public contracts (interfaces) shared between modules.

• app-calculo
  Implements business logic and provides a concrete implementation of the public API.

• app-financeiro
  Consumes the public API using ServiceLoader, enabling loose coupling and plugin-like behavior.

• app-logging
  Cross-cutting logging module shared across implementations.

The system demonstrates how to design a modular Java application with:

• clear contracts
• decoupled implementations
• dynamic service loading
• strict module encapsulation
