Zip files

In a project, I need zip file and append to separated folders.

public static void main(String[] params) throws IOException {
 List<String> srcFiles = Arrays.asList("E:\\file1.jar", 
   "E:\\file2.jar");
 FileOutputStream fos = new FileOutputStream("E:\\targetfile.zip");
 ZipOutputStream zipOut = new ZipOutputStream(fos);
 for (String srcFile: srcFiles) {
  File fileToZip = new File(srcFile);
  System.out.println(fileToZip + ", canRead:" + fileToZip.canRead());
  ZipEntry zipEntry = new ZipEntry(String.valueOf(srcFiles.indexOf(srcFile)) + "/" + fileToZip.getName());
  zipOut.putNextEntry(zipEntry);

  FileInputStream fis = new FileInputStream(fileToZip);
  IOUtils.copy(fis, zipOut);
  IOUtils.closeQuietly(fis);
 }
 IOUtils.closeQuietly(zipOut);
 IOUtils.closeQuietly(fos);
}
