Sorting array list of classes

[mike karl]

this is basically the short hand version of my class, just a question, how can i use my setOrder method to set the order for customer, amount, and date instead of writing 3 different methods for each one

public class Report implements Iterable<Bill> {

	public static enum reportsCreated implements java.util.Comparator<Bill> {
		BY_CUSTOMER {

			@Override
			public int compare(Bill arg0, Bill arg1) {
				return (arg0.owner.name.compareTo(arg1.owner.name));
			}
		},
		BY_AMOUNT {...
		},
		BY_DATE {...
		};
	}

	List<Bill> listOfReports = new ArrayList<Bill>();

public void setOrder(List<Bill> a) {
		List<Bill> tempList = new ArrayList<Bill>();
		int reVal = 0;

		for (int i = 0; i < a.size(); i++) {
			for (int b = i; b < a.size(); b++) {
				reVal = reportsCreated.BY_CUSTOMER.compare(a.get(b), a.get(i));
				if (reVal > 0) 
					tempList.add(i, a.get(b));
			}
		}
		tempList.iterator();
	}

	@Override
	public Iterator<Bill> iterator() {
		Iterator<Bill> billed = listOfReports.iterator();
		return billed;
	}
}
