    try {

      fileOutputStream = new FileOutputStream(zipfile);
      zipOutputStream = new ZipOutputStream(fileOutputStream);
      // Create ZipEntry
      ZipEntry entry = new ZipEntry(inFile.getName());
      // Set position of stream to the start of entry data
      zipOutputStream.putNextEntry(entry);
      // Write data to zipOutputStream
      byte[] data = new byte[1024];
      int i;
      while ((i = fileInputStream.read(data)) != -1) {
        zipOutputStream.write(data, 0, i);
      // Closes the current ZIP entry and positions the stream for writing
      // the next entry
      zipOutputStream.closeEntry();
    } catch (IOException e) {
      e.printStackTrace();
    } finally {
      try {
        if (fileInputStream != null) {
          fileInputStream.close();
        if (zipOutputStream != null) {
          zipOutputStream.close();
      } catch (IOException e) {
        e.printStackTrace();
压缩目录中的所有文件和子目录
此示例以递归方式遍历目录中的所有文件，并使用ZipOutputStream将其写入zip文件。
