Dude in replace

[spinter]

I explain problem.

My program needs to know all numbers, possitive an negative

I know how to replace all the chars that aren't digits, but i dont know how to do for - that say a number is < 0 dont remove

Eg:

String s = " hello, -3World, My name Pedro234"

then i use

s.replaceAll("\\D" , " ");


and the result is :

3 234

but not

-3 234

this is because \\D remove all that arent a digit, i dont know a form to do it without removing - ç


thx to all

You could use String.split() with a regex that matches both positive and negative numbers. Something like "-?[1-9][0-9]*", although I don't remember off the top of my head if the '-' would need to be escaped there.

Yes, it would need escaping.

Well.. I found one solution through that link. One the first hits actually. :)

And actually, my reasoning was backward... using split with a regex like the one I suggested would give you everything except the numbers you're interested in. You'd want to use that regex with a Matcher.
