Getting illegal character range in regex :java -

i have simple regex pattern verifies names. when run illegal character range error. thought escaping "\s" allow space compiler still complaining.

public boolean verifyname(string name) {     string namepattern = "^[\\p{l}]++(?:[',-\\s][\\p{l}]++)*+\\.?$";     return name.matches(namepattern); }

and error think shouldn't occurring since name might contain anny of these [',-\\s]

so not understanding?

you can't have range "from , whitespace". perhaps meant escape -?

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

things work:

"[ ',-]"  "[',\\- ]"
