How to get multiple regex matches in Java?

问题

How can I find all substrings that match a regex in Java? (Similar to Regex.Matches in .Net)

回答1:

Create a Matcher and use find() to position it on the next match.

Here is a code sample:

int countMatches(Pattern pattern, String str) {
  int matches = 0;
  Matcher matcher = pattern.matcher(str);
  while (matcher.find())
    matches++;
  return matches;
}
