- the WHAT in the name
- the HOW in the code, and

Sometimes there is no WHY. The reason and intentions are more than obvious (getters / setters, toString, equals methods etc.).
Writing JavaDoc for the obvious cases should be considered as defect...
Thanks Kai Windmöller for the suggestion / comment!
