- Java 11 or higher
- Maven or Gradle (depending on your build tool preference)
- IntelliJ IDEA or another preferred IDE
Create a config.properties file in the src/main/resources directory with the following content:
apiKey = YOUR_API_KEY
Replace YOUR_API_KEY with your actual API key from ExchangeRate-API.
Add the following dependencies to your pom.xml:
<dependencies>
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.8.8</version>
</dependency>
<!-- Add other dependencies as needed -->
</dependencies>
Add the following dependencies to your build.gradle:
dependencies {
implementation 'com.google.code.gson:gson:2.8.8'
// Add other dependencies as needed
}
If you prefer to add the JAR files directly to your project, download the Gson Jar and add it to your project
Use your build tool to compile and build the project. For Maven, run:
mvn clean install
For Gradle, run:
gradle build
Upon running the application, you will be presented with a terminal menu to choose conversion options. Follow the prompts to enter the value and perform currency conversion
Here is an example of how to use the application:
