hello again.
i have a quick question about bitwise operators.
how detailed can the questions about them get?
are we supposed to know how to add bits of a character integer?
also, what about hexidecimal numbers?
are we expected to know all about them too??
these are a definate crutch for me and if they are an integral part of the test, i'll need to concentrate on them.
can anyone offer any insight or advice?
thank you.

I think you need to know how the bitwise operators effect ints.
From what I've understood you also need to know how to convert to and from hexadecimal as well as octal.
I don't remember any hex or oct questions on my exam, but I did have some bitwise operators.

Hi Donny,
There are some questions on the exam that involve octal and hex numbers so you need to understand how they work. If you see any questions which require converting from one to the other they usually involve small numbers.
I have some notes on converting between binary/octal/decimal/hex at http://www.janeg.ca/scjp/oper/binhex.html
Hope that helps.

Hi Jane,
Thanks for the site reference. I'm fairly new to the Ranch, and this was my first visit to your site. It's great. Well organized; succinct. Very much appreciate your section on java.io. And tips and traps!
Thanks for your work.
Chuck
