How to remove all non alphanumeric chars from a String without remove @ symbols

currently using this regex: s.replaceAll("[^a-zA-Z0-9]", ""); however it removes values I need such as @ . , ! how can I include these in my regex so they do not get replaced with empty strings.

Cheers

Just add them to the regex. Note that . is a special character, so you'd have to escape it:

String newString = s.replaceAll("[^a-zA-Z0-9!@\\.,]", "");
