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

import java.io.File;
import org.apache.commons.io.FileUtils;
import org.apache.commons.io.comparator.PathFileComparator;
import org.apache.commons.io.comparator.SizeFileComparator;
import org.apache.commons.io.comparator.CleaningPathVisitor;

public class CleaningPathVisitorExample {
    public static void main(String[] args) {
        // Define the directory to clean
        File directory = new File("/path/to/directory");
        
        // Define the path comparator to use
        PathFileComparator pathComparator = new PathFileComparator();
        
        // Define the size comparator to use
        SizeFileComparator sizeComparator = new SizeFileComparator();
        
        // Create a new CleaningPathVisitor instance
        CleaningPathVisitor visitor = new CleaningPathVisitor(pathComparator, sizeComparator);
        
        // Visit all files in the directory
        FileUtils.visitFileTree(directory, visitor);
        
        // Get the cleaned files
        List<File> files = visitor.getFiles();
        
        // Do something with the cleaned files
        for (File file : files) {
            System.out.println(file.getName());
        }
    }
}

In this example, we are using the CleaningPathVisitor class to clean all the files in a specific directory that match certain conditions.

We define the directory to clean, and set a path comparator and a size comparator to use. The visitor will remove the files that match the conditions specified by the comparators.

Once the visit is finished, we get the cleaned files and do something with them.

It's worth noting that this class doesn't define any conditions or filters to remove the files, it uses the comparators passed to the constructor to decide which files should be removed.
