While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

Without the specific diagram provided, it is difficult to explain it in detail. However, I can provide a general explanation of the Clean Architecture concept.

Clean Architecture is a software architectural pattern that aims to create a separation of concerns and maintainability in software systems. It promotes the idea of designing software systems with clear boundaries and layers, where each layer has its own responsibilities and dependencies.

Typically, Clean Architecture consists of several layers:

1. Presentation Layer: This layer represents the user interface or the external interfaces through which users interact with the system. It includes components such as controllers, views, and presenters.

2. Application Layer: This layer contains the business logic of the application. It coordinates between different components and implements use cases or application-specific operations.

3. Domain Layer: This layer represents the core business logic and contains entities, domain objects, and business rules. It is independent of any external frameworks or technologies.

4. Infrastructure Layer: This layer deals with external dependencies such as databases, web services, or third-party libraries. It provides implementations for data access, network communication, and other infrastructure-related operations.

The arrows in the diagram usually represent dependencies between layers. The direction of the arrow indicates that one layer depends on another layer for its functionality or resources.

The main idea behind Clean Architecture is to enforce a clear separation between these layers so that changes in one layer do not affect other layers. This allows for better testability, maintainability, and flexibility in software systems.

It's important to note that there can be variations in how Clean Architecture is implemented based on specific requirements or frameworks used in Java development.

what about the entities? Is that like public classes?

[merry cipher]

Entities are objects or concepts that have their own unique existence and attributes. In the context of software development, entities often represent real-world objects or concepts that need to be modeled and manipulated within a system.

Entities can be thought of as the building blocks of an application's data model. They encapsulate data and behavior related to a specific concept or object, and they are often used to represent database tables or document collections in the backend.

While entities can be similar to public classes in object-oriented programming, they are not necessarily limited to just classes. Entities can also include other types of data structures like structs or records, depending on the programming language or framework being used.

In summary, entities are representations of real-world objects or concepts within a software system, and they serve as the foundation for modeling and manipulating data.

[cinder void]

so if i understand correctly

the entitiy is basically the data you are manipulating in your program right

for instance lets say we got a grocery store and then class customer and class stock.

customer and stock would be the entities?

[patent abyss]

In such a app, entities are often database entities, ie classes representing database tables

[cinder void]

could you give an example

[cinder void]

like would this not be correct

[patent abyss]

You may have a person table in the database, you may also have a corresponding person class entity in java

[cinder void]

and then use case would be how the client would be using the program right

[patent abyss]

Wdym

Entities are internal

[cinder void]

my bad i was referring to use case interactor

[patent abyss]

Wdym

[cinder void]

so like yk the use case interactor

in application business rules

whats that for
