What is Currency Converter?

A currency converter is a software code designed to convert one currency into another, allowing users to check their corresponding values. It can be in the form of a website or a mobile app and is based on current market or bank exchange rates. The main purpose of a currency converter is to simplify the process of converting one country's currency into another, providing users with accurate and up-to-date exchange rates.

The Problem Statement

The problem statement of this system is to reduce human efforts in recognizing and converting currency amounts. Previously, humans were required to manually recognize the amount of currency and convert it, which was time-consuming and prone to errors. The objective of the currency converter system is to develop a program that can automatically determine the amount of money and convert it into other currencies without the need for human supervision.

Objectives of the System

The main objective of the currency converter system is to create a program that can accurately calculate and convert currencies, such as RM to USD or Euro, USD to RM, and Euro to RM. The system aims to provide users with a convenient and efficient way to convert their currencies by allowing them to input the currency type and value, and then displaying the converted amount at the end of the program.

Solution to the Problem

To solve the problem of manual currency recognition and conversion, a system is created that can automatically calculate and change currency values. The system takes input values for the currency type and choice, which include RM, Euro, and USD. Based on the chosen currency, the total value for the new currency is calculated using predefined exchange rates. The system utilizes Java programming language and a graphical user interface (GUI) for ease of use.


In conclusion, a currency converter system provides a convenient and efficient way for individuals and businesses to convert currencies. By automating the process of currency recognition and conversion, it reduces human efforts and minimizes errors. The system can be further improved by offering more currency options and enabling multiple currency conversions at a time. Overall, a currency converter system simplifies currency exchange and enhances the user experience.

Appendix One: Program Code

The program code for the currency converter system is implemented using the GUI builder in NetBeans. The interface is designed to be user-friendly and intuitive. The code includes the necessary imports, variable declarations, and conditional statements for currency conversion. The program uses exchange rates to calculate the converted amount based on the chosen currency. The appendix provides a detailed overview of the program code.

Appendix Two: Program Manual

The program manual provides step-by-step instructions on how to use the currency converter system. It includes a video demonstration of the user interface and explains the process of entering the amount, selecting the currency type, and converting it to the desired currency. The manual aims to guide users in utilizing the system effectively and efficiently.
