Zip Multiple excel files Java

Question

I have to read and write Multiple excel files with POI and use ZipOutputStream to download. The code below archives file in D disk, but how do I use Apache POI to create and write excel files then archive it by ZipOutputStream?

public void zipFiles(HttpServletResponse response, Workbook workbook, String fileName) throws IOException {

    response.setStatus(HttpServletResponse.SC_OK);
    response.addHeader("Content-Disposition", "attachment; filename=\""+ fileName +".zip\"");

    ZipOutputStream zipOutputStream = new ZipOutputStream(response.getOutputStream());
    // create a list to add files to be zipped
    ArrayList<File> files = new ArrayList<>(2);


    files.add(new File("D://兵庫_WEB申請書.xls"));
    files.add(new File("D://兵庫_取消申請書.xls"));
    // package files
    for (File file : files) {
        zipOutputStream.putNextEntry(new ZipEntry(file.getName()));
        FileInputStream fileInputStream = new FileInputStream(file);
        IOUtils.copy(fileInputStream, zipOutputStream);
        fileInputStream.close();
        zipOutputStream.closeEntry();
    }    
    zipOutputStream.close();
}
