Link is not useful.

the hyperlink appears to be broken - the trailing ')' has been dropped. Copy and paste the full text of the link and it will be ok.

For the SCJP exam, you do not need to know what the term "cohesion" means or what "cohesive classes" are, so I will move this topic to a more appropriate forum.

??? It's in the K&B book and has a big bold headline (p. 151), I quote, Coupling and Cohesion (Exam Objective 5.1), quote end.

Yep, you do need to know a little Coupling and Cohesion. Perhaps this post will have to be moved again

Ok, moderators are not perfect either, I'll move it back again.

Cohesion is explained fairly in K & B book, if you read that I think one should be able to understand clearly.

My understanding is that, cohesion is to make sure that a class takes care only one definitive purpose. The whole responsibility is to represent and perform single functionality. For e.g if you want to write a class which would help in generating reports, it should be doing only report related stuff and nothing more.

Hope that helps.
