Question

The question is how do you detect 5 digits following each other in string. Ergo finding US postal code.

Side note: I’d like to use the code with GWT so there are limitations on regex and third party libraries. Otherwise I would just use net.sourceforge.jgeocoder.

Answer 1

\\d{5} as a regex I believe will be a starting point

Code:

String[] tokens = string.split("\\d{5}");  
// check token length.
