Using the HttpURLConnection class

Hi!! I am a 20 year old, studying Computer Science. We have been given an assignment to write a Java program that does the following:

Displays information about a file URL like tis type, encoding, length, dates of creation, last modification and expiry. Also, the request method, response message and response code for a Web URL are to be displayed.

We have managed to solve the first part of this question. But the latter half still remains to be done. Please help!!!
