What is the Difference Between MVP and MVC in Computer Programming?

What is MVP?

MVP stands for Model-View-Presenter, and it is a software design pattern used in computer programming. It is a variation of the Model-View-Controller (MVC) pattern, and it is used to separate the presentation layer from the business logic. The presenter acts as a mediator between the view and the model, and it is responsible for updating the view when the model changes. The presenter also handles user input and updates the model accordingly.

What is MVC?

MVC stands for Model-View-Controller, and it is a software design pattern used in computer programming. It is used to separate the presentation layer from the business logic. The controller is responsible for handling user input and updating the model accordingly. The view is responsible for displaying the model to the user. The model is responsible for storing the data and providing an interface for the controller and view to interact with it.

What is the Difference Between MVP and MVC?

The main difference between MVP and MVC is that in MVP, the presenter is responsible for updating the view when the model changes, while in MVC, the controller is responsible for updating the view when the model changes. Additionally, in MVP, the presenter is responsible for handling user input and updating the model accordingly, while in MVC, the controller is responsible for handling user input and updating the model accordingly.

Example of MVP and MVC in Code

The following code examples demonstrate the differences between MVP and MVC in code. The first example is an example of MVP:

class Presenter {
  private Model model;
  private View view;
  
  public Presenter(Model model, View view) {
    this.model = model;
    this.view = view;
  }
  
  public void onModelChanged() {
    view.update(model.getData());
  }
  
  public void onUserInput(String input) {
    model.update(input);
  }
}

The following example is an example of MVC:

class Controller {
  private Model model;
  private View view;
  
  public Controller(Model model, View view) {
    this.model = model;
    this.view = view;
  }
  
  public void onModelChanged() {
    view.update(model.getData());
  }
  
  public void onUserInput(String input) {
    model.update(input);
  }
}

Summary

MVP and MVC are both software design patterns used in computer programming. The main difference between them is that in MVP, the presenter is responsible for updating the view when the model changes, while in MVC, the controller is responsible for updating the view when the model changes. Additionally, in MVP, the presenter is responsible for handling user input and updating the model accordingly, while in MVC, the controller is responsible for handling user input and updating the model accordingly.
