DefaultFileComparator

public class DefaultFileComparator extends Object implements Serializable, Comparator
Compare two files using the default {@link File#compareTo(File)} method.

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 {@link #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 {@link #DEFAULT_REVERSE} singleton instance: 

File[] array = ...
Arrays.sort(array, DefaultFileComparator.DEFAULT_REVERSE);
