Java Programming

I have a list of words, one to each line, and each word has a single character at the end that denotes its part of speech. Therefore, I'm trying to write a regular expression that will match a single character at the end of line, so I can parse through this data.

I can't just use something like [N$] because it will just match the first 'N' from the end of the line, not just lines that end in N. So I want something that will match a single character at the end of a line.

So if my data contained something like:
BounceN
BouncerV

I would want the regular expression to match 'N' at the end of a line to match just "BounceN" and not "BouncerV".

Thanks for you time, and thanks in advance to anyone that can help.
