Java DirectoryFileComparator-class And Method Code Example

Here is an example of how to use the DirectoryFileComparator class from the package in Java:


public class Example {
    public static void main(String[] args) {
        File[] files = ...
        Arrays.sort(files, DirectoryFileComparator.DIRECTORY_COMPARATOR);

In this example, we are sorting an array of File objects using the DirectoryFileComparator.DIRECTORY_COMPARATOR constant. This comparator sorts files in the following order:

  • Directories come before files
  • Directories and files are sorted by their name

The Arrays.sort() method is used to sort the files array using the DirectoryFileComparator.DIRECTORY_COMPARATOR constant as the comparator.

It's worth noting that the DirectoryFileComparator class is an extension of AbstractFileComparator class, that uses the File class's natural ordering to compares files. The DIRECTORY_COMPARATOR constant is an instance of this class, that is configured to work as described above.
