I'm new to regular expressions I'm doing a java project and I'm trying to specify a string of characters that only include alphabetic characters plus, some special characters such as ö
, ä
, å
and ü
.
How can I specify all these in regex? So far I have this but it does not work:
return s.matches("^[a-zA-Z]*$ && [öäå]");
update:
ok so with this expression return s.matches("^[\\\\p{L}\\\\p{Nd}]*$");
I get all characters including ö and Ä but not å and ü
You don't need to use the AND operator in regex expressions.
return s.matches("^[a-zA-Zöäåü]*$");
That should do the trick.
请尝试以下操作: "^([a-zA-Z]+|([öäå])+)[a-zA-Z]*$"
可以尝试这样的事情^[a-zA-Zöäå]*$
