Java DefaultFileComparator-class And Method Code Example
Here is an example of how to use the DefaultFileComparator class from the org.apache.commons.io package in Java:
import java.io.File;
import org.apache.commons.io.comparator.DefaultFileComparator;
public class Example {
public static void main(String[] args) {
File[] files = ...
Arrays.sort(files, DefaultFileComparator.DEFAULT_COMPARATOR);
}
}
In this example, we are sorting an array of File objects using the DefaultFileComparator.DEFAULT_COMPARATOR constant. This comparator sorts files in the following order:
- Directories come before files
- Files are sorted by their name
- If the names are the same, the files are sorted by their path
The Arrays.sort() method is used to sort the files array using the DefaultFileComparator.DEFAULT_COMPARATOR constant as the comparator.
It's worth noting that the DefaultFileComparator class is an extension of AbstractFileComparator class, that uses the File class's natural ordering to compares files. The DEFAULT_COMPARATOR constant is an instance of this class, that is configured to work as described above.
