newbie: match non numeric non whitespace value

Thread view:

usgog@yahoo.com - 07 Feb 2007 19:28 GMT

I want to detect whether the java String has any non-numeric and non-
whitespace char. For example,
"12 34" returns false
"1234" returns false
"12a3" returns true
" a 12 3" returns true

Can I use [^0-9\\s]? If not, what does it mean?

Here, try looking for something in the methods of the String class

http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html

I'm thinking you should be able to use the "matches" method to do what
you want if you can figure out the regular expression business.

Thanks for the reply. The regular expression business is the thing
that I am asking for help. :)

So basically you want to know if there are any alpha characters in the
string. So, why not just use ([a-zA-Z]) in the regex expression?

I think [a-zA-Z] won't cover i18n characters.

Try "\\p{L}". Read

Study it.
