public class DefaultFileComparator extends Object implements Serializable
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
DEFAULT_COMPARATOR
singleton instance:
List<File> list = ... ((AbstractFileComparator) DefaultFileComparator.DEFAULT_COMPARATOR).sort(list);
Example of doing a reverse sort of an array of files using the
DEFAULT_REVERSE
singleton instance:
File[] array = ... ((AbstractFileComparator) DefaultFileComparator.DEFAULT_REVERSE).sort(array);
