It is very important you check for null and empty strings especially if you are accepting input from an html INPUT box.

Code: 
int i;
Integer j;
String formElement = request.getParameter("formElement");
if (formElement != null && !formElement.trim().equals("")) {
  
    /* to convert to a primative int */
    i = Integer.parseInt(formElement);

    /* to convert to an Integer object */
    j = new Integer(formElement);
}
