I have some code that sorts a list like so:

Vector<String> my_list = new Vector<String>();

        Comparator<String> c = new Comparator<String>() {

            public int compare(String object1, String object2) {
                if (object1 == null)
                    return -1;
                if (object2 == null)
                    return 1;
                object1 = object1.toLowerCase();
                object2 = object2.toLowerCase();
                return object1.compareTo(object2);
            };
        };

Collections.sort(my_list, c);

This seems like a lot of code for such a common operation.

Collections.sort( my_list, String.CASE_INSENSITIVE_ORDER );

Throws NullPointerException if the list has any nulls.
