My Code is

        String trans = null;
            try {
                GoogleAPI.setHttpReferrer("https://localhost/oauth2callback");
                //GoogleAPI.setHttpReferrer("https://www.googleapis.com/language/translate/v2");
                GoogleAPI.validateReferrer();
            } catch (Exception ex) {
                Logger.getLogger(GoogleTransalte.class.getName()).log(Level.SEVERE, null, ex);
            }
        try {
        GoogleAPI.setKey("ugCHXLVC8UEDojKqSU3gzCOZ");
            trans = Translate.DEFAULT.execute("Hello", Language.ENGLISH, Language.HINDI);
            } catch (GoogleAPIException ex) {
            Logger.getLogger(TranslateView.class.getName()).log(Level.SEVERE, null, ex);
        }
