How to compress generated selenium automation reports into a zip file

In order to share the generated selenium webdriver reports to team or clients ,we have to zip the results folder.
In this post, I will explain how can we compress generated automation reports into a zip file using java.
find the below sample code for the same.
Sample Code:
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;

public class ZIPFile {
   
    List<String> filesListInDir = new ArrayList<String>();

    //Method for ZIP folder to specific Directory
    public  void zipDirectory(File dir, String zipDirName) {
        try {
            populateFilesList(dir);
            //now ZIP files one by one
            //create ZipOutputStream to write to the ZIP file
            FileOutputStream fos = new FileOutputStream(zipDirName);
            ZipOutputStream zos = new ZipOutputStream(fos);
         
            for(String filePath : filesListInDir){
                //For ZipEntry we need to keep only relative file path, so we used substring on absolute path
                ZipEntry ze = new ZipEntry(filePath.substring(dir.getAbsolutePath().length()+1, filePath.length()));
                zos.putNextEntry(ze);
                //Read the file and write to ZipOutputStream
                FileInputStream fis = new FileInputStream(filePath);
                byte[] buffer = new byte[1024];
                int len;
                while ((len = fis.read(buffer)) > 0) {
                    zos.write(buffer, 0, len);
                }
             
                zos.closeEntry();
                fis.close();
            }
            zos.close();
            fos.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
   
    //This method populates all the files in a directory to a List
    public  void populateFilesList(File dir) throws IOException {
        File[] files = dir.listFiles();
        for(File file : files){
            if(file.isFile()) filesListInDir.add(file.getAbsolutePath());
            else populateFilesList(file);
        }
    }

   //Usage
   public static void main(String[] args) throws InterruptedException{
ZIPFile zip = new ZIPFile();
        File filename = new File("E:/WorkSpace/Practice/test-output");
        zip.zipDirectory(filename, "AutomationReports.zip");
System.out.println("Zipping of AutomationReports successfully");

 }
 

  }
