Java 谷歌API翻译返回错误

我有一部分代码是使用GoogleAPI翻译的，我的代码是这样写的

package pp;

import com.google.api.GoogleAPI;
import com.google.api.translate.Language;
import com.google.api.translate.Translate;


public class tr
{
    public static void main(String[] args) throws Exception{
        GoogleAPI.setHttpReferrer("http://code.google.com/p/google-api-translate-java/");
         GoogleAPI.setKey("AIzaSyBi7y4EgC0B-Q9UZg-tOzsOI0sLQ8F1Oow");

        String result = Translate.DEFAULT.execute("hello", Language.ENGLISH, Language.ARABIC);

        System.out.println(result);
        System.out.println("succeeded");


    }


    }

但是当我运行它时，我得到了这个错误

调试结果： 错误：[google api translate java]检索翻译时出错

运行结果
