Question about Comparators

Gregg asked
Last Modified: 2013-11-23
Is it possible to use the same Comparator class to compare any attribute of type String?

I have a person object with attributes:

String: firstName, lastName, address1, city, state, zip

Integer: personID

Id like to be able to sort by any one attribute (firstname, lastname, and city for example).

Do i create a comparator class for each? FirstNameComparator, LastNameComparator, CityComparator, etc...

Or is it possible to create a comparator that accepts string? Is that what generics does?
