Stripping extra white space from a string

Question

I am trying to strip extra spaces from a string, so it there are 2 or more spaces between a word I want to remove all but one. I am trying the following code
getStringTwo().replaceAll("/\s+/is","");
but all I get is an error saying Invalid escape sequence
Thanks

This strips out all the whitespace. I ended up
getting round it by walking through the string and
checking the values of each char and comparing that
to the next value. What a wast of effortt A small modification of my earlier post gives -
public class Test040320a
    public static void main(String[] args)
        String str = "this    is       a \t test";
        str = str.replaceAll("\\s+"," ");
        System.out.println(str);
}
