The Java API for regular expressions states that \s will match whitespace. So the regex \\s\\s should match two spaces.

Pattern whitespace = Pattern.compile("\\s\\s");
matcher = whitespace.matcher(modLine);
while (matcher.find()) matcher.replaceAll(" ");

The aim of this is to replace all instances of two consecutive whitespace with a single space. However this does not actually work.

Am I having a grave misunderstanding of regexes or the term "whitespace"?
