How can I get a parameter request to ignore the case of the user entered text

In my URL if the user enters in Type I have the following code:

String type= (request.getParameter("Type") != null) ? request.getParameter("Type") : request.getParameter("ty");

I would like to ignore the case that the user entered. For example a use case can be that the user enters Type, TYPE, TyPe, TYpe, tyPe, or Ty, tY, TY, ty. I want that to just to ignore the case have have it be set with my code. I tried to convert it to lower case but it did not work I get an error. Here is what I tried.

String type= (request..toLowerCase().getParameter("Type") != null) ? request.getParameter("Type") : request.getParameter("ty");

This did not work.

Converting a request to lower-case doesn't make any sense. Converting a string to lower case does.

In any case, I think what you're asking is to get a list of parameters, e.g.,

ServletRequest.html#getParameterNames()

Enumeration<String> paramNames = request.getParameterNames();

Then iterate over that list of parameter names, call toLowerCase() on them, and make comparisons as your business logic dictates.

You might also use getParameterMap() which does what you'd expect.
