How do you Invert signed numbers?

A simple question: How can I invert the sign of an integer? ie) convert -12 to +12? No doubt there is a really simple way to do this, but I'm stumped, I cannot find anything and I've been working on this program all day.
I'll be very grateful to anyone who can let me know if Java provides a way to do this, or point me in the right direction if it takes some tweaking of binary numbers using the Math package or something.
