public class HttpClientExample {

    public static void main(String[] args) {
    try {
        // 1. Configure and build HttpClient
        HttpClient client = HttpClient.newBuilder()
            .version(HttpClient.Version.HTTP_2)
            .connectTimeout(Duration.ofSeconds(30))
            .build();

        // 2. Prepare request payload
        String requestBody = "{\"title\": \"Bug in auth session\", \"body\": \"Need to verify token expiration handling\", \"labels\": [\"bug\", \"priority\"]}";

        // 3. Build HttpRequest
        HttpRequest.Builder requestBuilder = HttpRequest.newBuilder()
            .uri(URI.create("https://api.github.com/repos/octocat/Hello-World/issues"))
            .timeout(Duration.ofSeconds(30))

            .POST(HttpRequest.BodyPublishers.ofString(requestBody));
        HttpRequest request = requestBuilder.build();

        // Synchronous execution
        HttpResponse<String> response = client.send(request, HttpResponse.BodyHandlers.ofString());

        System.out.println("Status Code: " + response.statusCode());
        System.out.println("Response Body:\n" + response.body());
    } catch (Exception e) {
        System.err.println("HTTP Client Error: " + e.getMessage());
        e.printStackTrace();
    }
