This Java tips illustrates a method of copying one file to another file through channel. A channel is created both on source as well as destination and then the file is copied between those two channels.

   try {
           // Create channel on the source
           FileChannel srcChannel =
             new FileInputStream("srcFilename").getChannel();
      
           // Create channel on the destination
           FileChannel dstChannel =
             new FileOutputStream("dstFilename").getChannel();
      
           // Copy file contents from source to destination
           dstChannel.transferFrom(srcChannel, 0, srcChannel.size());
                   // Close the channels
         srcChannel.close();
         dstChannel.close();
       } catch (IOException e) {
         //TODO catch exception
       }
