import java.net.URL;
import java.net.URLDecoder;
import java.util.HashMap;
import java.util.Map;

public class UrlTest {
    public static void main(String[] args) {
        try {
            String s = "https://graph.facebook.com/me/home?limit=25&since=1374196005";
            URL url = new URL(s);
            String query = url.getQuery();
            Map<String, String> data = new HashMap<String, String>();
            for (String q : query.split("&")) {
                String[] qa = q.split("=");
                String name = URLDecoder.decode(qa[0]);
                String value = "";
                if (qa.length == 2) {
                    value = URLDecoder.decode(qa[1]);
                }

                data.put(name, value);
            }
            System.out.println(data);
        } catch (Exception e) {

URL url = new URL("https://graph.facebook.com/me/home?limit=25&since=1374196005");

String[] parts = {
   url.getProtocol(), 
   url.getUserInfo(), 
   url.getHost(), 
   url.getPort(), 
   url.getPath(),
   url.getQuery(), 
   url.getRef() 
};
