Negative octal or hexadecimal

[Andry Dub]

Ara there negative octal or hexadecimal numbers on SCJP 5 exam?
If they are, how they ara represented?

Hi Andry,

I'm not sure what you mean. Negative octal and hexadecimal literals are written the way you'd probably expect, i.e. -020 or -0xcafe. If you're referring instead to the underlying two's complement bit representation, you don't need to know this for SCJP 1.5.

Hope this helps.
