I am new to Alfresco. I want to download a document from the service.  How to get name, description, and Author from the content object. 
        
           Content[] readResult = contentService.read(
               new Predicate(new Reference[]{node}, STORE, null), Constants.PROP_CONTENT);
          Content content = readResult[0];
