How can you retrieve the data sent by the FORM displayed by following HTML page code?

<html>
<body>
<form action="/myapp/SaveServlet" method="POST">
<input type="file" name="name">
<input type="submit" value="POST">
</form>
</body>
</html>

1)request.getParameter("name");

2)request.getAttribute("name");

3)request.getInputStream();

4)request.getReader();

5)request.getFileInputStream();

The correct answer given is 3 and 5. I agree.

But why the answer given 1 is wrong, because there is a parameter name in the html.

This is from Enthuware.

Please advise.

1. In the given example html input "type" is "file" and not "text".
2. getParameter() returns you a String.
3. Being we are tring to access the file request object, we will not get String. Hence this answer is wrong.

The getFileInputStream()? Such a method doesn't exist in the HttpServletRequest and in the ServletRequest API. Where did you find it?

The answer should be 3 and 4...we can use both InputStream getInputStream() and BufferedReader getReader()
