How to match tab and newline but not space with REGEX?

Question

I am trying to match "tab" and "newline" meta chars but without "spaces" with REGEX in Java.

\s matches evrything i.e. tab, space and new line... But, I don't want "space" to be matched.

How do I do that?

Thanks.

One way to do it is:

[^\\S ]

The negated character class makes this regex to match anything except - \\S (non-whitespace) and " "(space) character. So, it will match \\s except space.

Explicitly list them inside [...] (set of characters):

"[\\t\\n\\r\\f\\v]"
