How can I implement a Google API for java? [closed]

So I want to build an api for google reader, but really do not know where to begin.

Initially, I was trying to build a auto-screening application to pick reading-worthy articles for me from my subscriptions. So I need google reader api. After search a while, I found there is no satisfying one for me. Then I thought it would be fun to create an api for myself and following developers.

For init开发者_JAVA百科ial development, I need this api to retrieve article list and URLs of them. Any ideas about how to do this? I will try out suggestions and report later.
