Is it costly to do req.getParameter() multiple times??
Joined: Jan 17, 2001
Hello all, Please have a look at the statement below? Do u think there is an overheade in the statement (since req.getParameter() is done twice when the paramenet is not null). String sSearchBy = req.getParameter("SearchBy")==null?"" String)req.getParameter("SearchBy"); Is there a better way to optimize the code?? Thanks, Sajee Joseph

You wrote: String sSearchBy = req.getParameter("SearchBy")==null ? "" : ( String)req.getParameter("SearchBy"); Sure, there's plenty of ways to improve this, for example:
Personally, I don't particularly like to hard code the default value ("") in situations like this, so I'd probably take a few minutes to write something like:
The in my code I could use the more expressive:
The biggest advantage of this approach is that it makes it so simple to appy a default value when reading parameters, that I'm much more likely to consider doing it every time, and not risk risk run-time failures through laziness.
