Java Regex Help on \p{Punct} -

i have next regexes, 1 \p{punct} , other 1 without

snippet (1):

add(\s[\w\p{punct}]+)+(\s#\w+)*

snippet (2):

add(\s[\w]+)+(\s#\w+)*

if input "add purchase egg #grocery testing", result matching in (1) not matching in (2). thought happening?

your sec regex allows # @ start of lastly matched word in string stating "add" while in sentence # exists in word wasn't last. \p{punct} character class includes # character class [\w\p{punct}] lets match

\w alphabetic characters, digits , _ and \p{punct} punctuation: 1 of !"#$%&'()*+,-./:;<=>?@[]^_`{|}~

which lets #grocery matched if not lastly word.
