Question

I have the following string:

See it now! .5..%..off your purchase!.Only today.

I would like it to be

See it now! 5% off your purchase! Only today.

Which is:

every special character followed by zero or more spaces and one or more periods, will be replaced with the special character and a space. In case of a number and 2 periods, it will be replace with spaces only

How can I do it?

Answer 1

\Try this

String resultString = subjectString.replaceAll("\\B[ .]+", " ");

This matches one or more spaces or periods which are preceded by a non-word boundary. These are then replaced by a single space.

Edit

Based on the amended question:

String resultString = subjectString.replaceAll("\\B[ .]+|(\\d)\\.+", "$1 ");

Also matches a digit followed by one or more periods. The periods are replaced by a single space.
