Using Form Data

• Using form data allows us to dynamically generate a web page based on user input.
• Use the GET and POST methods we've talked about before.
• The server kindly performs the URL deconding for us, so that we can just access the variables via the getParameter() method of ServletRequest.
• Pass in the parameter (key) name.
• Returns the value if one exists, an empty string of no value exists for that key, and null if no such key exists.
• Parameter names are case sensitive.
• getParameterValues() returns a String array of the values.
• getParameterNames() returns the keys as an enumeration.
