Servelts - 4a : ServletData question

Hi,

I'd like to verify if there are any Parameters in servletData being passed into a doAction method. Is it just a matter of checking what getParameter or getParameters returns? Do these return NULL if they don't contain the Parameter(s)?


Thanks,

Jeremy

Jeremy, it's been a long time since I did these assignments, but I believe the answer to your first question is yes, but you have to do more than just "check" what is in the parameter. And I think the answer to the second question is also yes, because the parameters are strings, so if they aren't there then they would be null.
 
It is sorta covered in the JavaRanch Style Guide.
