Question

I have a String which has many segments separated by a dot (.) like this:

codes.FIFA.buf.OT.1207.2206.idu

I want to get a substring only until second dot, like codes.FIFA.

How to substring just until the second dot?

Answer 1

 Matcher m = Pattern.compile("^(.*?[.].*?)[.].*")
                    .matcher("codes.FIFA.buf.OT.1207.2206.idu");
 if (m.matches()) {
      return m.group(1);
 }
