爪哇 - 關於谷歌日曆API V3

Question

https://developers.google.com/google-apps/calendar/instantiate?hl=zh-CN

I would like to use Google Calendar API v3, but in this example, I can't find these libraries: 

import com.google.api.client.auth.oauth2.draft10.AccessTokenResponse; 
import com.google.api.client.googleapis.auth.oauth2.draft10.GoogleAccessProtectedResource; 
import com.google.api.client.googleapis.auth.oauth2.draft10.GoogleAccessTokenRequest.GoogleAuthorizationCodeGrant; 
import com.google.api.client.googleapis.auth.oauth2.draft10.GoogleAuthorizationRequestUrl; 

Perhaps they are too old and deprecated? and where can I get the latest examples for authorization codes?

FYI：我已經得到了谷歌從他們要更新過時的文檔和示例使用新的API（V3）的例子作出正式答覆。
