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

import java.io.File;
import org.apache.commons.io.filefilter.AgeFileFilter;

public class Example {
    public static void main(String[] args) {
        // create a File object for the directory to be listed
        File directory = new File("/path/to/directory");

        // create an AgeFileFilter object with the cutoff date
        long cutoff = System.currentTimeMillis() - (24 * 60 * 60 * 1000); // 24 hours ago
        AgeFileFilter fileFilter = new AgeFileFilter(cutoff);

        // list all files that are older than the cutoff date
        File[] olderFiles = directory.listFiles(fileFilter);
        for (File file : olderFiles) {
            System.out.println(file.getName());
        }
    }
}

This example will filter all files that are older than 24 hours from a directory and print the names of all the older files. You can customize the cutoff date to any date you want.
