Difference between Java Regular Expression Pattern and .Net Framework

Is it possible to indicate the main differences in regex patterns

There are many differences that are given here .

The most important of them are:

  • In Java strings you need to avoid all backslashes ( @"\s"becomes "\\s")
  • Java does not support groups of captured names.
  • Java does not support endless repetition inside lookbehinds.
  • Java does not support conventions ( (?(?=regex)then|else))
  • Unicode -.
