Money Calculator is a Java application that simplifies currency conversion efficiently. Using the Model-View-Controller (MVC) design pattern and the Observer pattern, the application provides an intuitive interface for performing currency conversions with ease.
-
Currency Conversion: Allows the user to enter the amount in a source currency and select the destination currency to get the converted amount.
-
Automatic Update: Implements the Observer pattern to automatically update the interface when conversion data changes.
-
User-Friendly GUI: Developed with Java Swing, the user interface is easy to understand and use.
The code follows the MVC pattern for clear and modular organization:
-
Model: Contains business logic and manages exchange rates. The
MoneyCalculatorclass performs conversion calculations and maintains the history. -
View: Represents the user interface. The
MoneyDisplayView, MoneyView, and MoneyEditViewclasses handle the presentation and data input for conversions. -
Controller: Manages interactions between the user and the application. The
MoneyEditControllerclass handles user events and updates the model and view accordingly.
The Observer pattern is used to allow the view to update automatically when exchange rates change.
-
An API is used to obtain updated exchange rates.
-
Relevant components are located in the WebService package.
