sorting - Java: sort a String array, whose strings represent int

Question

I have String[] array like

{"3","2","4","10","11","6","5","8","9","7"}

I want to sort it in numerical order, not in alphabetical order.

If I use

Arrays.sort(myarray);

I obtain

{"10","11","2","3","4","5","6","7","8","9"}

instead of

{"2","3","4","5","6","7","8","9","10","11"}

Answer 1

Try a custom Comparator, like this:

    Arrays.sort(myarray, new Comparator<String>() {
        @Override
        public int compare(String o1, String o2) {
            return Integer.valueOf(o1).compareTo(Integer.valueOf(o2));
        }
    });
