Use google-api-translate-java but error

[GoogleCodeExporter]

What steps will reproduce the problem?
I've created following class in the eclipse
package com.translate;

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

public class aaa {

    public static void main(String[] args) throws Exception {

        GoogleAPI.setHttpReferrer("http://www.google.com");
        GoogleAPI.setKey("AIzaSyAhwmTOURyWNpx2jrfnCpMywejOSwlpVa8");
        try {
            String translatedText = Translate.DEFAULT.execute("Hello",
                    Language.ENGLISH, Language.CHINESE_TRADITIONAL);

            System.out.println(translatedText);
        } catch (GoogleAPIException e) {
            e.printStackTrace();
        }

    }

}
I'm trying to use google-api-translate-java api but error.

What is the expected output? What do you see instead?
expected output:你好
but see error:

Did you checkout this service? I thought it's free but actually not, so check 
this one first and try again maybe can work ,or consider using Microsoft BING 
translator It's free by translating 500,000 word/month :D
