Do you mean something beyond this:

?

Yeah beyond that ........

Like ~i=(-i)-1

This is an equation I got while doing a mock exam.

Something like this for ^,>>,<< and >>.

Swapna and all,

Just a reminder that if you're studying for the SCJP 5.0 exam you don't have to worry about bit shifting and bit twiddling topics - they were removed for the 5.0 exam

However, if you're studying for 1.4... well... carry on!

Spot false dilemmas now, ask me how!
