Regular expression: use any chars as delimiter except a-zA-z and “.”

in.useDelimiter("[^a-zA-Z]+");
this expression can use any non-letter char as delimiter (eg, input abc@, abc will be stored; inputabc., abc will be store).
However, I don't want to ignore "." because I want to use it to end the input.
How can I modify the regular expression above?.

. is a wildcard in regex's syntax meaning "any character". If you want to use it as a "real" character, you need to escape it with a :
in.useDelimiter("[^a-zA-Z.]+");
// Escapting here -------^

Actually, you don't need to escape the.in that context (a character class). The only characters that do / might need to be escaped in a character class are^,[,],&and-.
