I have a regular expression with a pound # modifier.
What does \# mean in a regular expression? What does the # mean in a regular expression? Is it possible that Java is just ignoring these invalid modifiers?
\#is not a valid regex modifier. It would technically be a way to escape a#character, IF the#meant anything significant in Java’s regex. Because it doesn’t, Java is just ignoring this invalidity and reading it as a#instead of throwing you an error.
