Comparing numbers as string

[Marianne Hagaseth]

Hi,
Which function to use to be able to return "1","2","3","10","11", and not 
"1","10","11","2","3"  (String values)?

public static class RegulationsComparator implements Comparator<Regulation> {
    @Override
    public int compare(Regulation p, Regulation q) {
        Ordering<Regulation> byRegulationNumber = new Ordering<Regulation>() {
          public int compare(final Regulation p, final Regulation q) {
            return 
Ordering.natural().nullsFirst().compare(p.getRegulationNumber(),q.getRegulationNumber());
            }
        };
        return byRegulationNumber
                .compound(Ordering.<Regulation>natural())
                .compare(p, q);
    }
}



Med vennlig hilsen / Best regards,
