I'm looking for any potential gotchas I might have missed. A couple of points I came across:-
From K & R int  x , y ; //defines two arrays of ints int x , y; //defines one array of ints and one int primitive K and R states that if  follows the type then all variables in the declaration are arrays. Otherwise the  must follow each array name in the declaration. From Dan's exam:- int a3,a4; does not compile, because the  must be placed after the type or identifier.
None of these seem to be covered in S & B. Am I just getting pre-exam jitters or what?

Don't sweat this type of stuff too much. The exam's purpose isn't to give you every possible permutation of an array declaration to see if you have a java compiler built into your brain. The exam is a good test of your array knowledge, but it doesn't do this by using gimmicky questions.
