• Treat the contents of a loop as a separate block.
  Read
  while (xenum.hasMoreElements()) {
      /* [...] */
      if (object instanceof Resource) {
          /* [...] */
          if (!copy(is, os))
              /* [...] */
      } else if (object instanceof InputStream) {
          /* [...] */
          if (!copy((InputStream) object, os))
              /* [...] */
      } else if (object instanceof DirContext) {
          /* [...] */
      }
  }
  
  as
  while (xenum.hasMoreElements()) {
      /* [...] */
  }
  
• In a body of a structure, consider its controlling expression as an asserion
      if (!links.contains(next)) {
          links.add(next);
      }
