It seems that you can add elements to a java.util.List that is backed by an array. For example, you could try this:

import java.util.Arrays;
import java.util.List;

public class ListSample {
    public static void main(String[] args) {
String[] a = {“foo”, “bar”};
List l = Arrays.asList(a);
l.add(“baz”);
System.out.println(l.get(0));
System.out.println(l.get(1));
    }
}
