i do not know if there is something that can do it automatically but let's say you have the following regex:
"a number of 5 digits" then "2 letters" then "a hyphen" and then "a digit"
what you can do is something like that:
define the vars that will allows you to pick a value for each part of the generated value
this means you will have:
final int[] DIGITS = new int[]{0;1;2;3;4;5;6;7;8;9};
final char[] LETTERS = new char[]{'a', 'b', ... 'z'};
final char HYPHEN = '-';
once you have those vars, all you have to do is to use "Random" class to retrieve a random value from DIGITS and LETTERS
append them all in the correct order , without forgetting to append the HYPHEN and you have your value
