How to Configure APIKey in Java for Google Cloud Translation

[Chetan]

Hi
How can I configure Apikey in my Java class. I am using google-cloud-translate 1.12.0 in Maven Entry. Appreciate any help, Thanks in advance

Also, as a start I am using one of google GIT published code

/**
     * Detect the language of input text.
     *
     * @param sourceText
     *            source text to be detected for language
     * @param out
     *            print stream
     */
    public static void detectLanguage(String sourceText, PrintStream out) {
        Translate translate = createTranslateService();
        List<Detection> detections = translate.detect(ImmutableList.of(sourceText));
        System.out.println("Language(s) detected:");
        for (Detection detection : detections) {
            out.printf("\t%s\n", detection);
        }
    }

    /**
     * Create Google Translate API Service.
     *
     * @return Google Translate Service
     */
    public static Translate createTranslateService() {
        return TranslateOptions.newBuilder().build().getService();
    }

    public static void main(String[] args) {
        detectLanguage("Hello", System.out);
    }

Error it gives
{
  "error": {
    "code": 403,
    "message": "The request is missing a valid API key.",
    "errors": [
      {
        "message": "The request is missing a valid API key.",
        "domain": "global",
        "reason": "forbidden"
      }
    ],
    "status": "PERMISSION_DENIED"
  }
}

For security reasons, the use of service account is preferred over API keys. You can follow this guide for service accounts or this GitHub example for API keys.
