import java.net.URL;

public class APIClient {
    public static void main(String[] args) {
        try {
            // Replace "YOUR_API_ENDPOINT" with the actual API endpoint URL
            URL url = new URL("YOUR_API_ENDPOINT");
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("GET");

            int responseCode = connection.getResponseCode();
            System.out.println("Response Code: " + responseCode);

            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            StringBuilder response = new StringBuilder();
            String line;

            while ((line = reader.readLine()) != null) {
                response.append(line);
            }
            reader.close();

            System.out.println("Response Body: " + response.toString());
