Regex Invalid Escape Sequence on Split String

Question

I'm attempting to make my String array split on whitespace or any punctuation besides the dash character. This is my attempt:

String[] temp = lowerCased.split("\p{Blank}\\\p{Punct}&&[^-]]");

I'm getting the Invalid Escape Sequence and I figure it has to do with Java's need for a double backslash, but I can't pinpoint where exactly it's going wrong. I put it into one of the Regex emulation programs and it seemed to get the result I was going for.

Answer 1

The backslashes are not escaped properly, try this. There is also a left square bracket missing at the beginning.

String[] temp = "".split("[\\p{Blank}\\\\p{Punct}&&[^-]]");
