Examples of java.util.regex.Matcher.group()

java.util.regex.Matcher.group()
Returns the input subsequence matched by the previous match.
For a matcher m with input sequence s, the expressions m.group() and s.substring(m.start(), m.end()) are equivalent.

Note that some patterns, for example a*, match the empty string. This method will return the empty string when the pattern successfully matches the empty string in the input.
@return The (possibly empty) subsequence matched by the previous match,in string form @throws IllegalStateException If no match has yet been attempted, or if the previous match operation failed
