Order ArrayList of dates in decending or ascending order

Question

I have an array list of Dates and I want to order it by dates in ascending and descending order. Could anyone please provide a complete code snippet for this ? I have seen many questions like this but could not find a suitable answer.

List will be like this

         List<Date> dates= new ArrayList<Date>();

Any kind of help will be appreciated , Many thanks,

Since Date already implements Comparable, you can simply use:

Collections.sort(dates);

to sort in ascending order, and for descending order:

Collections.sort(dates, Collections.reverseOrder());
