Accessing zips and jars using Java Part 2

这是第一篇文章的代码片段:

  ZipFile zip = new ZipFile(fileName);

  // Process the zip file. Close it when the block is exited.

  try {
     // Loop through the zip entries and print the name of each one.

     for (Enumeration list = zip.entries(); list.hasMoreElements(); ) {
        ZipEntry entry = (ZipEntry) list.nextElement();
        System.out.println(entry.getName());
     }
  }
  finally {
     zip.close();
  }
