The Java MVC (Model View Controller) design pattern separates an application's business logic and view, with the model managing information and notifying observers of changes, the view displaying data and taking user input, and the controller handling requests and forwarding them to the appropriate handler to access the model and render it to various user interfaces.

- 1. Java MVC (Model View Controller) Design Pattern Model View controller is a classical design pattern used in applications who needs a clean separation between their business logic and view who represents data. MVC design pattern isolates the application logic from the user interface and permitted the individual development, testing and maintenance for each component. This design pattern is divided into three parts. 1. Model- This component manages the information and notify the observers when the information changes. It represents the data when on which the application operates. The model provides the persistent storage of data, which manipulated by the controller. 2. View- The view displays the data, and also takes input from user. It renders the model data into a form to display to the user. There can be several view associated with a single model. It is actually representation of model data. 3. Controller- The controller handles all requests coming from the view or user interface. The data flow to whole application is controlled by controller.
