public class DefaultFileComparator extends Object implements Comparator, Serializable
This comparator can be used to sort lists or arrays of files by using the default file comparison.
Example of sorting a list of files using the DEFAULT_COMPARATOR singleton instance:
List<File> list = ... Collections.sort(list, DefaultFileComparator.DEFAULT_COMPARATOR);
Example of doing a reverse sort of an array of files using the DEFAULT_REVERSE singleton instance:
File[] array = ... Arrays.sort(array, DefaultFileComparator.DEFAULT_REVERSE);
