Looking for Regex that removes everything but the number

I am trying to use java's string.replaceAll() or replaceFirst() methods in order to edit data from a pdf document.The line of data that is returned is:

21/1**E (6-11) 4479 77000327633 (U)

I wish to only store the 77000327633 into a variable and looking for the correct regex to replace everything else with "". I've tried searching around but nothing seems to give me my desired outcome.


Answer Source

It could be done like this:

String value = "21/1**E (6-11) 4479 77000327633 (U)";
Pattern pattern = Pattern.compile(".* (\\d{11}) .*");



NB: This assumes that your number has 11 digits and that there is a space before and after.

NB2: It is not meant to be perfect it is only to show the idea which is here to define a global pattern with a group and replace everything by the content of the group
