java regex for "any symbol" that's neither word nor number nor space

Question

As the title says: I want the input to be one or more symbols that is not in the union of letters, numbers and white space. So basically any of ~!@#, etc. I have

"^(?=.*[[^0-9][^\w]])(?=\\S+$)$"

I know I could negate the appropriate set, but I don't know how to create my super set to start with. Would the following do?

"^(?=.*[(_A-Za-z0-9-\\+)])(?=\\S+$)$"

Answer 1

Maybe you're looking for \p{Punct}, which matches any of !"#$%&'()*+,-./:;<=>?@[]^_`{|}~.

String re = "\\p{Punct}+";

Answer 2

The class:

[^\w\s]

This will match any non-alphanumeric/non-whitespace character.

Java String:

String regex = "[^\\w\\s]";
