Here is an example of how to use the CopyDirectoryVisitor 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.CopyDirectoryVisitor;

public class CopyDirectoryVisitorExample {
    public static void main(String[] args) {
        // Define the source directory
        File srcDir = new File("/path/to/src");
        // Define the destination directory
        File destDir = new File("/path/to/dest");
        
        // Define the path comparator to use
        PathFileComparator pathComparator = new PathFileComparator();
        
        // Define the size comparator to use
        SizeFileComparator sizeComparator = new SizeFileComparator();
        
        // Create a new CopyDirectoryVisitor instance
        CopyDirectoryVisitor visitor = new CopyDirectoryVisitor(srcDir, destDir, pathComparator, sizeComparator);
        
        // Visit all files in the source directory
        FileUtils.visitFileTree(srcDir, visitor);
    }
}

In this example, we are using the CopyDirectoryVisitor class to copy all the files in a source directory to a destination directory.

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

Once the visit is finished, all the files from the source directory will be copied to the destination directory.

It's worth noting that this class doesn't define any conditions or filters to copy the files, it
