public class Main {
    public static void main(String[] args) {
        try {
            FliptEvaluationClient fliptClient = FliptEvaluationClient.builder()
                    .url("http://localhost:8080")
                    .authentication(new ClientTokenAuthentication("secret"))
                    .build();

            Map<String, String> context = new HashMap<>();
            context.put("fizz", "buzz");

            Result<VariantEvaluationResponse> result =
                    fliptClient.evaluateVariant("flag1", "entity", context);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            // Important: always close the client to release resources
            if (fliptClient != null) {
                fliptClient.close();
            }
        }
