Java Sorting based on Enum constants

I used following to sort my List<theEnum> in an ascending order, and it worked fine for me.

Collections.sort(toSortEnumList, new Comparator<theEnum>() {
                @Override
                public int compare(theEnum o1, theEnum o2) {
                    return o1.toString().compareTo(o2.toString());
                }
            });

Enum<E> implements Comparable<E> via the natural order of the enum (the order in which the values are declared). If you just create a list of the enum values (instead of strings) via parsing, then sort that list using Collections.sort, it should sort the way you want. If you need a list of strings again, you can just convert back by calling name() on each element.
