public void zipFile(File srcFile, File zipFile) throws IOException {
 try (FileInputStream fis = new FileInputStream(srcFile);
   ZipOutputStream zos = new ZipOutputStream(new FileOutputStream(zipFile))) {
  zos.putNextEntry(new ZipEntry(srcFile.getName()));
  int len;
  byte[] buffer = new byte[1024];
  while ((len = fis.read(buffer)) > 0) {
   zos.write(buffer, 0, len);
  }
  zos.closeEntry();
 }
}
