3. Lazy Singleton Pattern

Technologies Used: 1.Java 2.Java Swing 3.Spring MVC 4.MySQL

Architecture Explained

1. App.java: Contains the main method and is called first when we start an application. It instantiates MainJFrame(View) and Controller(MainController).

2. View: Designed using Swing. Layout used is Card Layout.

3. Controller: Whenever an event is dispatched then controller is called. For example: a  button is clicked. Validation are done in this part. Like if user want to see an student  he/she should enter a valid id.

4. MiddleWare: Controller calls the middleware. It takes the action like to add a student, delete a student and then call database MySQL to update the changes. Implemented using Factory Design Pattern and Lazy Singleton Design Pattern.

5. Model:  Classes that represent data. This data is then added to database.
