I think we could agree there are a limited amount of SCEA studyguides out there, compared to SCJP studyguides. I knew this book (below) has had mixed reviews/ratings but bought it anyway, due to lack of alternative studyguides.
Has anyone used this book, and if so, what are your honest impressions of it for the SCEA exam?

If you have a class that merly uses the services of another class you do not show it in an association or on a class diagram. for example:
I take a book out of the library on a date. The lendable object is associated with a specific date object called the due date which is a member of the lendable object. I may also use the Date class to obtain the string representation of the date to use for a report given nightly to the librarian which shows the books taken out that day. This is not an association only a uses relationship which we do not need to show on a class diagram. There is no semi-permanent relationship between the Date class and the report class. There is between the lendable and the due date!
There are many classes that fit into the non-associated just used category. I reversed engineered Sun's Pet store example and was very surprised how many non associated classes there are. All of the exception classes for example are used when needed not associated. Many of the factory classes are associated only to the DAO they create not the rest of the class diagram, so once they create their representative DAO's they out of stuff until they are needed again. They are associated to those DAO's however.
