Getting illegal character range in regex :java

Question

I have a simple regex pattern that verifies names. But When I run it I get illegal character range error. I thought by escaping \"\\s\" it will allow a space but the compiler is

Answer 1

You can't have a range "from , to whitespace". Perhaps you meant to escape -?

\s is not a space, it's [ \t\r\n\v\f] (space, tab, carriage return, newline, vertical tab or a form feed).

Things that will work:

"[ ',-]"

"[',\\- ]"
