I know what you mean about the java.util package.
On a slightly related note I’m studying for the Business Components Developer exam and you need to learn serveral interface specs.
Not a problem.

Ah, an unnecessary subtlety.
Why have the same thing twice – why is one object extended and the other not? Why?
The Java libraries are riddled with this and it makes passing the certifications unecessarily hard. I want to slap whoever did this but have to control myself.
