Can anyone explain me this code?

Question

import org.apache.http.message.BasicNameValuePair;

private String getServerData(String returnString) {               
InputStream is = null;

String result = \"\";
         


        

Answer 1

In the end you're doing a http POST request with the field "year" having the value "1970".

Just like a webform posting that year would.

A bit extra: The BasicNameValuePair looks quite aptly named: Its a very simple (basic) group of two things (pair) that serve as a formfield (name) and its contents (value).

The httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); adds that combination of year and 1970 to the HttpPost object, but with encoding (so there are no 'illegal' things in there).
