การเปลง request.getParameter() เป็น Int : Converting request.getParameter() result to int and String


I would like to convert result from request.getParameter("myInt") to int and request.getParameter("myStr") to String. I was under the impression that the result type from getParameter() is of type String, but I'm either wrong or I'm doing something wrong (I'm new to Java, so there is a pretty good chance that I'm doing something wrong).

If I do something like this:

Code

String resMyStr = request.getParameter("myStr");

I can see that request.getParameter("myStr") has a value however resMyStr remains null.

For the int result I was also doing:

Code

int resMyInt = Integer.getInteger(request.getParameter("myInt")).intValue();

Again, I can see that request.getParameter("myInt") gets appropriate values such as 1, 2 and so on; however resMyInt just stays at 0.
