The NameFileComparator class available in Commons IO library that have feature for sorting file array by name,last modified date, size and many more.Files can be sorted in ascending and descending order, with case sensitivity or case insensitivity.

Import :

org.apache.commons.io.comparator.NameFileComparator

Code :

File directory = new File(".");
File[] files = directory.listFiles();
Arrays.sort(files, NameFileComparator.NAME_COMPARATOR)
