  public java.lang.String group()

  Comparing jdk-20-ga and jdk-21+35

  group

  public String 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.

  Specified by:

  group  in interface MatchResult

  Returns:

  The (possibly empty) subsequence matched by the previous match, in string form or null if a matcher with a previous match has changed its Pattern , but no new match has yet been attempted

  Throws:

  IllegalStateException - If no match has yet been attempted, or if the previous match operation failed

• ✗

  public java.lang.String group(int arg0)

  Comparing jdk-20-ga and jdk-21+35

  group

  public String group (int group)

  Returns the input subsequence captured by the given group during the previous match operation.

  For a matcher m, input sequence s, and group index g, the expressions m.group( g) and s.substring( m.start( g ),  m.end( g)) are equivalent.

  Capturing groups are indexed from left to right, starting at one. Group zero denotes the entire pattern, so the expression m.group(0) is equivalent to m.group() .

  If the match was successful but the group specified failed to match any part of the input sequence, then null is returned. Note that some groups, for example (a*) , match the empty string. This method will return the empty string when such a group successfully matches the empty string in the input.

  Specified by:

  group  in interface MatchResult

  Parameters:

  group - The index of a capturing group in this matcher's pattern

  Returns:

  The (possibly empty) subsequence captured by the group during the previous match, or null if the group failed to match part of the input or if the matcher's Pattern has changed after a successful match, but a new match has not been attempted

  Throws:

  IllegalStateException - If no match has yet been attempted, or if the previous match operation failed

  IndexOutOfBoundsException - If there is no capturing group in the pattern with the given index
