Simple way to sort strings in the (case sensitive) alphabetical order

Question

I need to sort list of strings in the alphabetical order:

List list = new ArrayList();
list.add(\"development\");
list.add(\"Development\");
li

If you don't want to add a dependency on Guava (per Michael's answer) then this comparator is equivalent:

private static Comparator ALPHABETICAL_ORDER = new Comparator() {
    public int compare(String str1, String str2) {
        int res = String.CASE_INSENSITIVE_ORDER.compare(str1, str2);
        if (res == 0) {
            res = str1.compareTo(str2);
        }
        return res;
    }
};

Collections.sort(list, ALPHABETICAL_ORDER);

And I think it is just as easy to understand and code ...

The last 4 lines of the method can written more concisely as follows:

        return (res != 0) ? res : str1.compareTo(str2);
