Which method should the servlet use to access the uploaded files?

A web application for business expense reporting allows uploading expense receipts. Multiple
receipts can be uploaded single step using one HTTP request. The servlet that processes the

request has been marked with the @MultipartConfig annotation.
Which method should the servlet use to access the uploaded files?

A.
HttpServletRequest.getParts()

B.
HttpServletRequest.getData()

C.
servletRequest.getParts()

D.
servletRequest.getAllParts()

Explanation:
The request.getParts() method returns collections of all Part objects. If you have
more than one input of type file, multiple Part objects are returned. Since Part objects are named,
the getPart(String name) method can be used to access a particular Part. Alternatively, the
getParts() method, which returns an Iterable<Part>, can be used to get an Iterator over all the Part
objects.
