How to Get a Monospaced Font

I'm trying to draw strings to a <JPanel>, and would like them to be
drawn in a font where each character has the same pixel width. I had
thought that "Courier" was such a font, so I wrote the following
program to verify that its characters do in fact have the same pixel
width, but when I tried running it I saw that they did not. For
example, the small "i" is very much narrower than the capital "W".
Can someone tell me a font I can use that might have a
chance of being monospaced?

I think I asked something similar to this before, and somebody told me
that different machines have different fonts, so I couldn't count on
getting an answer that was generally applicable. If that is true, how
can I find out which fonts my machine has? Any information would be
greatly appreciated.
