Java SizeFileComparator-class And Method Code Example


Here is an example of how to use the SizeFileComparator class from the org.apache.commons.io package in Java:

import java.io.File;
import org.apache.commons.io.comparator.SizeFileComparator;

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

In this example, we are sorting an array of File objects using the SizeFileComparator.SIZE_COMPARATOR constant. This comparator sorts files based on their sizes. The Arrays.sort() method is used to sort the files array using the SizeFileComparator.SIZE_COMPARATOR constant as the comparator.

You can also pass a boolean value as argument to the SizeFileComparator constructor indicating whether the sort should be done in reverse order. For example:

SizeFileComparator comparator = new SizeFileComparator(true);

This will sort the files in reverse order of their sizes.

It's worth noting that the SizeFileComparator class is an extension of AbstractFileComparator class, that uses the File class's natural ordering to compares files and sorts them based on their sizes, in the order specified in the constructor.
