Every mock exam I have taken so far includes something about wrapper classes, mostly identifying them. The same thing applies java.util collections (like identifying classes and interfaces suitable for a certain problems). My question is: I can't find anything in the SUN's exam objective that mentions anything about:
a) wrapper classes. I say so because even
though java.lang is included in the exam,
only certain Math functions and immutability
of strings are included
b) collections API. The only thing they mention
is identifying what colletion
classes/interfaces are suitable
I did a search on this board and I have read posts saying that c-tors and API's should be known.
Can someone clear this?
Also, for all the
SCJP's, has anyone every gotten any questions involving the API of wrapper classes and collections.
many thanks in advance, Jamil
