When I develop the java program,I can learn the class I need from
help system very easy!.
but in scjp exam,I think it's not allowed to access the help system!So should I remember most of the classes in JDK?

You need to know the hierarchy of classes.
For e.g, Runtime Exception is a subclass of Exception
I have taken some mock tests and a lot of questions
revovle around class hierarcy.
Good luck.

Hi Dragon,
No, you don't have to remember all of them but you do need to know the ones in java.lang, the basic classes available in java.awt and java.awt.event (especially the layout manager) and those in java.io and java.util. For the java.io and java.util packages it's more important to remember the heirarchy and the superclasses.
Hope that helps.

Dragon,
A basic understanding of the classes will lead u to a situation where u don't have to remeber them rather u'll easily recall them as soon as u need them. The SCJP exam tests if u can recall the most necessary classes instantly and hence knowing the hierarchy of classes and related interfaces (package-wise) will help u in real life also....but its also true that one can code upto a level without having to remember them. The exam doesn't permit that...
