I am not sure if anyone here has experience in this, but I am working with web services and Json.

I am trying to obtain my current geographic information (city and state) by using the Weather Underground ([Weather Forecast & Reports - Long Range & Local | Wunderground | Weather Underground](http://www.wunderground.com/)) API ([API | Weather Underground](http://www.wunderground.com/weather/api/)). I want to use the geolookup feature ([API | Weather Underground](http://www.wunderground.com/weather/api/d/docs?d=data/geolookup)) to print out zipcode, city, and state.

I started it, but I am not really sure where to go from here. How should I use the geolookup function? I already created a key.

```plaintext
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Scanner;

import com.google.gson.JsonElement;
// Requires gson jars
import com.google.gson.JsonObject;
import com.google.gson.JsonParser;

public class Wunderground {         
	/**
	 * @param args
	 * @throws Exception 
	 */
	public static void main(String[] args) throws Exception {
		// Get from http://www.wunderground.com/weather/api/
		String key;
		if(args.length < 1) {
			System.out.println("Enter key: ");
			
			Scanner in = new Scanner(System.in);
			key = in.nextLine();
		} else {
			key = args[0];
		}
		
		String sURL = "http://api.wunderground.com/api/" + key + "/conditions/forecast/q/19104.json";
		
		// Connect to the URL
		URL url = new URL(sURL);
		HttpURLConnection request = (HttpURLConnection) url.openConnection();
		request.connect();
		
		// Convert to a JSON object to print data
    	JsonParser jp = new JsonParser();
    	JsonElement root = jp.parse(new InputStreamReader((InputStream) request.getContent()));
    	JsonObject rootobj = root.getAsJsonObject(); // may be Json Array if it's an array, or other type if a primitive
    	
    	// Get some data elements and print them
    	double temp_f = rootobj.get("current_observation").getAsJsonObject().get("temp_f").getAsDouble();
		System.out.println(temp_f);
		
		String todayforecast = rootobj.get("forecast").getAsJsonObject().get("txt_forecast").getAsJsonObject().get("forecastday").getAsJsonArray().get(0).getAsJsonObject().get("fcttext").getAsString();
		System.out.println(todayforecast);
	}

}
