This week's book giveaway is in the OCMJEA forum. We're giving away four copies of OCM Java EE 6 Enterprise Architect Exam Guide and have Paul Allen & Joseph Bambara on-line! See this thread for details.
HttpServletRequest request; int userID = (new UserUtil(connection)).findByUserName(request.getRemoteUser()).getUserID();
I know that is not the cleanest code to read, but I have the idea that is efficient, because there are not new references created on the heap, then the anonymous object is ready for garbage collection. Now if I do something like:
HttpServletRequest UserUtil userUtil = new UserUtil(connection); String userName = request.getRemoteUser(); User user = userUtil.findByUserName(userName); int userID = user.getUserID();
will be as efficient that the code describe first?
I agree with Steve and Stefan - don't worry about it, just use the one that you find easier to read.

By the way, all objects are "anonymous" in the sense that they don't have names. The only things having names are the reference variables (which an object can have an arbitrary number being referenced by).
