// GET Example
HttpClient httpClient = HttpClient.newHttpClient();
HttpRequest httpRequest = HttpRequest.newBuilder(URI.create("https://localhost:8443/get")).GET().build();
HttpResponse<String> httpResponse = httpClient.send(httpRequest, HttpResponse.BodyHandler.asString());
HttpClient.Version version = httpResponse.version();
String body = httpResponse.body();
System.out.println(version);
System.out.println(body);
