Dear Siva and Seema,

In SCJP the accent of the mocks lied in analyzing
code.

In SCWCD with patterns it sounds to me that there
might be some schematic representation, maybe UML,
to depict a concept. Is it required to have some
knowledge of UML if this is the case?

Or are any other diagrams used?

Cheers,

Gian Franco

You do not need to know UML in order to handle SCWCD exams.

Most of the questions that related to SCWCD pattern are case-based.

The questions talk about the current situation, and what the user wants, and then you choose the suitable pattern (MVC, Front Controller, TransferObject, etc) for the situation.

No UML knowledge is required in order to answer the questions. But of course, if you know a bit, you may easier to understand the concepts.

Adding to what nicolas said,knowledge of UML helps in understanding the interacting components and strategies of a pattern. But for the exam it is not required. You can expect two kinds of questions from patterns: One that asks you to select the advantages(disadvantages) of a pattern from a list of things. Second could be the selection of the correct pattern for a given scenario.
