Nov 12, 2011 · Example in Java8 to sort by last modification time: .filter(f -> Files.isDirectory(f) == false) // exclude directories. .sorted((f1, f2) -> (int) (f1.toFile().lastModified() - f2.toFile().lastModified())); then you may convert sortedList to Array or continue using lambda expressions with .forEach: .forEach(f -> {do something with f (f is Path)}) .

you can use Collections.sort(fileList); to sort arraylist. Then use. for(File file:fileList) System.out.println(file.getName()); Collections.sort()

The order of returning the directories depends on your file system, not on Java. Some file systems always list file names in alphabetical order; others don't. There's not much to understand here; simply sort the files as you need.

In this section we will be showing source code on how to list files in ascending or descending order by filename. We will be using extensively the Collections class sort method. Calling the Collections.sort with only with one argument which is list, …

binary files and implements a radix sort algorithm. The program will deal with a binary input file, named Unsorted.bin, that contains a collection of data records of the following form: [ 8-byte non-negative integer | 4-byte integer ]

It’s important to recognize that the method to read a binary file must exactly match the order of the write and read statements of the method that wrote the binary file. For example, if the file contains records that consist of a String followed by an int followed by a double, then they must be written by a sequence consisting of

This Java tutorial describes how to sort an array of files according to their names using a Comparator from Commons IO.
