What This Project Does

The Money Calculator project is a currency conversion tool built using Java and Swing for the GUI. It fetches real-time currency exchange rates and enables users to:

1. Enter an amount and select source and target currencies to convert.
2. See the converted amount displayed immediately.
3. Maintain a scrollable history of all conversions for reference.

The application is divided into components, each responsible for specific tasks:

• Commands: Handles the execution and tracking of conversion actions.
• GUI: The graphical interface, including panels for user input and history display.
• Service Layer: Includes classes for fetching exchange rates and performing conversions.
• Configuration: Manages application settings such as default currencies.
