Can anyone please explain in detail what is the Difference between getParameter() and getAttribute().

getAttribute() returns an object so when ever we use a getAttribute() we have to cast the return type that is we have to convert it to the required type like string or int.getParameter always returns a string.

one more difference is where this 2 methods are used...getAttribute is used to get the values from the session and getParameter is used to get the values from the form.(html or a jsp file)
