solution to change the file ending with recursive search in path

import java.io.IOException;
import java.nio.charset.Charset;
import java.nio.charset.StandardCharsets;
import java.nio.file.FileSystems;
import java.nio.file.Files;
import java.nio.file.OpenOption;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.List;

import sun.awt.image.BytePackedRaster;

public class handleFileEndingMain {

    static int carriageReturnTotal;
    static int newLineTotal;

    public static void main(String[] args)  throws IOException
    {       
        processPath("c:/temp/directories");

        System.out.println("carriageReturnTotal  (files have issue): " + carriageReturnTotal);

        System.out.println("newLineTotal: " + newLineTotal);
    }

    private static void processPath(String path) throws IOException
    {
        File dir = new File(path);
        File[] directoryListing = dir.listFiles();

        if (directoryListing != null) {
            for (File child : directoryListing) {
                if (child.isDirectory())                
                    processPath(child.toString());

        } 


    }

    private static void checkFile(String fileName) throws IOException

        Path path = FileSystems.getDefault().getPath(fileName);

        byte[] bytes= Files.readAllBytes(path);
