    Building a Java project is one of the best ways to strengthen your programming skills and understand how concepts work together in real-world applications. Below is a step-by-step guide to creating a Currency Converter project using Spring Boot, which is beginner-friendly yet covers essential Java development skills.

    Step 1: Set Up Your Environment

    • Install JDK 17+ and set JAVA_HOME.

    • Install an IDE like IntelliJ IDEA or Eclipse.

    • Create a new Spring Boot project with dependencies: Spring Web Spring Security (optional for authentication) H2 Database Jackson (for JSON parsing)

    Step 2: Create the Project Structure

    Your package structure might look like:

    com.example.currencyconverter
    ├── controller
    ├── service
    ├── model
    └── repository
    Copied!

    Step 3: Implement the Model

    public class Conversion {
    private String fromCurrency;
    private String toCurrency;
    private double amount;
    private double result;

    // Getters and Setters
    }
    Copied!

    Step 4: Service Layer for API Integration

    Use a public API like ExchangeRate-API:

    @Service
    public class CurrencyService {
    private final RestTemplate restTemplate = new RestTemplate();

    public double convert(String from, String to, double amount) {
    String url = "https://api.exchangerate-api.com/v4/latest/" + from;
    Map<String, Object> response = restTemplate.getForObject(url, Map.class);
    Map<String, Double> rates = (Map<String, Double>) response.get("rates");
    return amount * rates.get(to);
    }
    }
    Copied!
