question about socket and information hiding

Hi,

I read the article Advanced Socket Programming ( http://java.sun.com/developer/technicalArticles/ALT/sockets/ )

there is something that I doesn't understand very well, this:

" ......This breaks information hiding and force tight coupling. A solution to this problem would be to write an interface that extends the Serializable interface and then have the SerializedObject class in Code Sample 8 implement the new interface. Using this technique, you only need to provide copies of the interface to the client and server, but not implementation. "

Can anyone explain it in a more easy way? with a example or so?
