I admit that I am not good with regular expression. If any of you is good with regular expression, could you please suggest a pattern that will help me?
This is the problem statement:
If an input String contains any of the following 16 characters (e.g. !, @, =, etc.) that that input String is invalid.

Check out character classes on the java.util.regex.Pattern Javadoc page.
