on USD facilitating retrievals and providing ease of updates. This program permits users to convert a specified amount, between any pair of supported currencies check exchange rates and dynamically add or update rates. By using USD as a pivot currency the system guarantees uniform and dependable outcomes.The application follows a menu-driven structure, improving user interaction by guiding them through conversion, rate viewing, and update options. It demonstrates important Java concepts such as collections, modular programming, input handling, and formatted output. This project highlights how simple Java programs can be applied to real-world financial tasks and can be further expanded with features like live API-based rates, a graphical interface, or database support .Overall, the Advanced Currency Converter demonstrates how core programming concepts like data structures, loops, conditional statements, and formatted output can be used to build a real-world, functional application. The project not only performs accurate conversions but is also flexible for future enhancements such as integrating real-time exchange APIs, adding a graphical interface, or expanding currency support. Thus, it stands as a meaningful example of applying Java programming to solve everyday financial needs.
