Sort an ArrayList of Strings that are numbers

Question

What is the fastest way to sort an ArrayList (in descending/ascending manner) that contains numbers, eg: { \"12\", \"3.5\", \"188\", \"33.03

Answer 1

You can use Collections.sort() on List, String is Comparable, but that comparison won't give you the right result.

Also you can define your own Comparator, and pass it to Collections.sort().
