Hello everyone, I come with a question because I am learning hexagonal architecture when, how and why do we use package-private in this architecture I would like someone to explain it to me in plain English or maybe someone knows a good tutorial on YouTube
hexagonal architecture?
In hexagonal architecture, the main goal is to separate the application core from external concerns such as frameworks or libraries. Package-private access level in Java allows classes within the same package to access each other's members, while restricting access from classes outside the package.
Using package-private visibility can be beneficial in hexagonal architecture when we want to limit the access of certain classes or methods to only components within the same package. This helps in achieving a cleaner and more maintainable codebase by encapsulating implementation details and preventing external components from directly accessing internal structures.
Package-private visibility is often used for defining interfaces or abstract classes that should only be implemented or extended within the same package, ensuring better encapsulation and reducing dependencies between different layers of the application. It also helps in enforcing architectural boundaries and keeping a clear separation of concerns within the codebase.
Overall, using package-private visibility in hexagonal architecture can help improve modularity, reduce coupling, and enhance overall code quality by restricting access to internal components and promoting a more structured and organized design.
