public class LastModifiedFileComparator extends Object implements Serializable
FileUtils.lastModifiedUnchecked(File)
).
This comparator can be used to sort lists or arrays of files by their last modified date/time.
Example of sorting a list of files using the
LASTMODIFIED_COMPARATOR
singleton instance:
List<File> list = ... ((AbstractFileComparator) LastModifiedFileComparator.LASTMODIFIED_COMPARATOR).sort(list);
Example of doing a reverse sort of an array of files using the
LASTMODIFIED_REVERSE
singleton instance:
File[] array = ... ((AbstractFileComparator) LastModifiedFileComparator.LASTMODIFIED_REVERSE).sort(array);
Serialization is deprecated and will be removed in 3.0.

file1
- The first file to compare.file2
- The second file to compare.public File[] sort(File... files)
This method uses Arrays.sort(Object[], Comparator)
and returns the original array.
files
- The files to sort, may be null.public List<File> sort(List<File> files)
This method uses List.sort(Comparator)
and returns the original list.
