How to get a substring matching a regular expression from another string?

Question

Couldn't seem to find anything Java-specific here in SO.

I'm trying to get at a MAC address.

For example:

String input = "9hin00:1b:63:84:45:e6n0hu";

I need to get "00:1b:63:84:45:e6"

where MAC address could be any set of characters, but always with the "..:..:..:..:..:.." pattern

You can use this regex for matching MAC address:

(?:[a-fA-F0-9]{2}:){5}[a-fA-F0-9]{2}
