 MVC Architecture


    MVC Architecture stands for Model, View, Controller a software design pattern commonly used for developing user interfaces that separates an application into three interconnected components. This separation helps organize code, making it easier to maintain, scale, and test.



Model (Data Layer)
  • Represent the data and the business logic of the application.
  • It is responsible for strong, retrieving and managing the data.
  • The model doesn't depend on how the data is displayed, it only handles data logic.
View (Presentation Layer)
  • Represents the user interface  what the user sees and interacts with.
  • it displays data from the model and sends user actions (like click or inputs) to the Controller.
Controller (Logic Layer)
  • Acts as the bridge between the View and the Model.
  • It receives input from the user(Via the View), processes it, and updates the Model or View accordingly.
  • It decides what happens when like which data to fetch and how it should be displayed.


How MVC Works (Flow Summary)

  1. User interacts with the view(e.g. clicks a button)
  2. Controller receives the input and interprets it.
  3. Controller requests or updates data from the Model. 
  4. Model sends the updated date back to the View.
  5. View refreshes the UI to reflect the new data. 


Benefits of MVC

  • Separation of concerns - Easier maintenance and testing
  • Reusability - Same Model can be used with different View.
  • Scalability -  Each part can be developed or modified independently.

Java Design Patterns

Java Design Patterns Java Design Patterns are reusable, well-tested solutions to common design problems in object-oriented programming. They act as templates that guide how to structure classes, create objects, and manage interactions in a clean and efficient way. Instead of reinventing solutions, developers follow these established patterns to write flexible, maintainable, and scalable Java applications. They also improve communication by giving developers a shared vocabulary. Overall, design patterns help produce high-quality, organized, and adaptable software. Design patterns in Java are generally grouped into three main categories, 1. Creational Design Patterns These patterns deal with object creation mechanisms, improving flexibility and reuse. Singleton    Ensures only one instance of a class exists, and provides a global access point. Factory Method  Defines an interface for creating objects, but lets subclasses decide which          ...

Application Programming Interface (API)

Application Programming Interface (API) What is Application Programming Interface ? Through an API, a program can ask another program for information or actions and get a response without having to understand the underlying workings of the other program. In the example for Application Programming Interface, a restaurant waiter is the best example. The reason for saying this is that the waiter position is similar to API. The waiter receives an order from you, the customer. Your request is communicated to the chef (the server) by the waiter (the API). After processing the request and preparing the food, the chef hands it to the waiter. It is returned to your table by the waiter (answer). In the same way, the API takes the request from the client and sends a request to the server and accordingly the response from the server is sent to the client by APL Why do We need APIs ? Building scalable, adaptable, and networked systems requires APIs. Developers depend on them for the following reaso...
