There is also a special group, group 0, which always represents the entire expression. This group is not included in the total reported by groupCount. Groups beginning with (? are pure, non-capturing groups that do not capture text and do not count towards the group total. (You'll see ...
capturing groups capture as normal. Backreferences match text captured during the same recursion as normal. When the regex engine exits from the recursion, all capturing groups revert to the state they were in prior to the recursion, except for the capturing group that was recursed to and has ...

Group 0 is the entire match, so group(0) (or just group()) returns the entire portion of the input that matched. The notion of parentheses or “capture groups” is central to regex processing. Regexes may be nested to any level of complexity. The group(int) method lets you retrieve ...
