How to untar a .tar.gz MultipartFile and add the files to List<File> or List<FileItem>

Question

I am sending .tar.gz MultipartFile in my api request, and I want to untar and store all the files in List<File> or List<FileItem>

So Far I have...

 public void importFilesTar(MultipartFile file) throws ContentRepositoryDaoException, Exception {
    List<File> files = new ArrayList<File>();
    List<FileItem> fileItems = new ArrayLis<FileItem>();
    
    InputStream in = file.getInputStream();
    GzipCompressorInputStream gzipIn = new GzipCompressorInputStream(in);
    TarArchiveInputStream tarIn = new TarArchiveInputStream(gzipIn);
    TarArchiveEntry entry;
    
    while ((entry = (TarArchiveEntry) tarIn.getNextEntry()) != null) {
        // Get each file from the .tar.gz, and add it to files (List<File>) or fileItems (List<FileItem>)
    }
 }

But I am unable to successfully untar, get the files and add it to list of File or FileItems. Thanks
