Given:
1. public class Fellowship {
2. public static void main(String[] args) {
3. // insert code here
4. }
5. }
6. class Numinor {
7. enum Members {
8. HOBBITS(48), ELVES(74), DWARVES(50);
9. int height;
10. Members(int h) {height = h; }
11. int getHeight() {return height; }

Ⅰ. int h0 = Numinor.Members.HOBBITS.getHeight();
Ⅱ. int h1 = Numinor.Members.getHeight();
Ⅲ. int h2 = Members.HOBBITS.getHeight();
Ⅳ. int h3 = Members.height;
