Answer / Sandeep Jaiswal
A multi-tier application in Java can be developed using various architectures such as Model-View-Controller (MVC), Service-Presentation (SP) or Model-View-ViewModel (MVVM). Here's an example of a simple MVC architecture:n
1. Model: Represents the business logic and data of the application.n - Entity classes (e.g., User, Product) to represent data structures.n - Service classes (e.g., UserService, ProductService) to perform operations on the entities.
2. View: Represents the user interface.n - JSP or JSF pages that define the UI structure and layout.
3. Controller: Acts as an intermediary between Model and View.n - Servlet or Spring MVC controller classes to handle requests, call services, and update models if needed.
