zip and unzip in java

Question

I know that it is an easy task, but after changing my code it stopped working and I can\'t get it back! I use two functions to zip and unzip, even though what it actually does i

Answer 1

Somehow I got it working, apparently it WAS stream-related... thanks for the help, everyone!

class zipper
{
     static byte[] buffer = new byte[4096];

     public static void unzip(File zipfile, File outputfolder)  throws Exception
     {
         JarFile zip = new JarFile(zipfile);

         Enumeration entries = zip.entries();
         while(entries.hasMoreElements())
         {
             JarEntry entry = (JarEntry) entries.nextElement();
             File unzipped = new File(outputfolder,entry.getName());

             if (entry.isDirectory() && !unzipped.exists())
             {
                 unzipped.mkdirs();
                 continue;
             }
             else if (!unzipped.getParentFile().exists())
                 unzipped.getParentFile().mkdirs();

             InputStream in = zip.getInputStream(entry);
             FileOutputStream fos = new FileOutputStream(unzipped);

             int count;
             while((count = in.read(buffer, 0, buffer.length)) != -1)
                 fos.write(buffer, 0, count);

             // clean up
             fos.close();
             in.close();
         }
   }

   public static void zip(File[] infiles, JarOutputStream jos) throws Exception
   {
       zip(infiles,"",jos);

       // clean up
       jos.flush();
       jos.close();
   }

   public static void zip(File[] infiles, String basefolder, JarOutputStream jos) throws Exception
   {
       for(int i=0; i
