Zipping folders recursively

Question

Hello. I'm new to Java.I have a program that zips a directory recursively, but the problem is with the empty folders.I need to keep the structure of the directory, even if there are empty folders.Can anyone help me, please?
Thank u in advance!
import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStreamReader;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;
public class Zipping {
public static void main(String[] a) throws Exception {
BufferedReader in = new BufferedReader (new InputStreamReader(System.in));
System.out.println("Enter the source directory/file name : ");
String source = in.readLine();
File src = new File (source);
if (src.isDirectory()) {
String zipFile = source + ".zip";
zipFolder (source, zipFile);
else {
int lastDot = source.lastIndexOf(".");
String zipFile;
if (lastDot != -1) {
zipFile = source.substring(0, lastDot) + ".zip";
else {
zipFile = source + ".zip";
zipFolder (source, zipFile);
static public void zipFolder(String srcFolder, String destZipFile) throws Exception {
ZipOutputStream zip = null;
FileOutputStream fileWriter = null;
fileWriter = new FileOutputStream(destZipFile);
zip = new ZipOutputStream(fileWriter);
addFileToZip("", srcFolder, zip);
zip.flush();
zip.close();
static private void addFileToZip(String path, String srcFile, ZipOutputStream zip) throws Exception {
File folder = new File(srcFile);
if (folder.isDirectory()) {
addFolderToZip(path, srcFile, zip);
else {
byte[] buf = new byte[1024];
int len;
FileInputStream in = new FileInputStream(srcFile);
zip.putNextEntry(new ZipEntry(path + "/" + folder.getName()));
while ((len = in.read(buf)) > 0) {
zip.write(buf, 0, len);
static private void addFolderToZip(String path, String srcFolder, ZipOutputStream zip) throws Exception {
//if ( src.isDirectory()) { 
File folder = new File(srcFolder);
String[] fileName = folder.list();
for (int i = 0; i < fileName.length; i++) {
if (path.equals("")) {
addFileToZip(folder.getName(), srcFolder + "/" + fileName, zip);
else {
addFileToZip(path + "/" + folder.getName(), srcFolder + "/" + fileName[i], zip);
