Java AndFileFilter-class And Method Code Example


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

import java.io.File;
import org.apache.commons.io.filefilter.AgeFileFilter;
import org.apache.commons.io.filefilter.FileFilterUtils;
import org.apache.commons.io.filefilter.HiddenFileFilter;
import org.apache.commons.io.filefilter.AndFileFilter;

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 a filter for files that are older than 24 hours and are hidden
        long cutoff = System.currentTimeMillis() - (24 * 60 * 60 * 1000); // 24 hours ago
        AgeFileFilter ageFilter = new AgeFileFilter(cutoff);
        HiddenFileFilter hiddenFilter = HiddenFileFilter.HIDDEN;

        // create an AndFileFilter object with the age filter and hidden filter
        AndFileFilter andFilter = new AndFileFilter(ageFilter, hiddenFilter);

        // list all files that match the age filter and hidden filter
        File[] matchingFiles = directory.listFiles(andFilter);
        for (File file : matchingFiles) {
            System.out.println(file.getName());
        }
    }
}

This example will filter all files that are older than 24 hours and are hidden from a directory and print the names of all the matching files. You can add more filter with AndFileFilter class.

This is just an example, you can also use FileFilterUtils.andFileFilter() to create AndFileFilter.

AndFileFilter andFilter = new AndFileFilter(ageFilter, hiddenFilter);

can be written as

AndFileFilter andFilter = FileFilterUtils.andFileFilter(ageFilter, hiddenFilter);
