In the coming chapters, let us see how we can use the MVC methodology within Struts2. The controller receives the input, it validates the input and then performs the business operation that modifies the state of the data model. The controller is responsible for responding to the user input and perform interactions on the data model objects.

It responds to the request from the view and it also responds to instructions from the controller to update itself. The model is responsible for managing the data of the application.

The View then uses the data prepared by the Controller to generate a final presentable response. Here the Controller receives all requests for the application and then works with the Model to prepare any data needed by the View. Creately diagrams can be exported and added to Word, PPT (powerpoint), Excel, Visio or any other document. You can edit this template and create your own diagram. A dialog box is a good example of a view. MVC is popular as it isolates the application logic from the user interface layer and supports separation of concerns.

Application data and logic (encapsulated by the model) should be independent of presentation logic (encapsulated by the views and controllers): Views are responsible for user input and output.
