Thank you... I think I have gone into PANIC mode and now nothing makes sense to me... You have confirmed what I thought was going on... Now if I can just learn to subtract ..

I saw something about this on oracle's site... I think you have to be 'registered' with oracle to access this part of the web site, but it is free... Here is the link: http://oracle.com/education/certification/index.html?starthere.html and it is the Oracle JAVA Developer I think you are talking about... Good luck (and if you could say a little prayer for me as I am taking my test in the am )

I took the Sun class SL275 and in that class the instructor introduced us to the mod operator - %. When used (z = x%y) z would be equal to the remainder of the division expression.
int z,x,y;
x = 12;
y = 5;
z = x%y;
z would be 2 (the remainder...)
so now I have been taking all these mock exams and every single one of them (perhaps out of date?!?) refers to this operand (%) as being (z = x%y) z = x - y until z is less than y or something crazy like that... All the helpful tools I have found refer to % as mod... They come up with the same number for z in the above examples... Have I been cramming too much? Is my brain going to EXPLODE? Could someone please clarify if these are the same or not...
Thank you!

I GET IT!!! Thank you so much for pointing me in the right direction... although some people might view the 'lesson' as a cheesy, I found it very helpful... Wonder what people will think when I start drawing mice on scratch paper for the test??
Thanks again!!

I am trying to study for the cert test (aren't we all) and after taking the SL-275 class from Sun I was feeling kinda good... until finding out that it would really help to understand binary stuff... right and left shift operators, when does the sign change, etc... Does anyone know of a good place to go to take a 'tutorial' on all things binary? I would appreciate it!!
