Matching non spaces in Java

I want to detect strings that contain non white space characters Now I'm trying:

!Pattern.matches("\\*\\S\\*",city)

But it doesn't seem to work Does anyone have any suggestions? I know I can trim a string and test whether it is equal to an empty string, but I'd rather do so

Solution

What do you think regular expressions match?

attempt

Pattern p = Pattern.compile( "\\S" );
Matcher m = p.matcher( city );
if( m.find() )
//contains non whitespace

The find method will search for partial matches, not exact matches This seems to be the behavior you need
