error when saving class

does anyone know why whenever I tried to save this class on eclipse it always gives me an error of save could not be completed

Reason:

Some characters could not be mapped using "Cp1252" character encoding. Either change the encoding or remove the characters which are not supported by the "Cp1252" encoding.

How do I resolve this?

If it is a compiler error, your compiler expects CP1252 characters on your source file based on your system locale setting but your actual encoding isn't. I would change the source encoding and recompile.
