     "vicinity" : "Mahalingapuram Main Road, Nungambakkam, Chennai"
  }

after parsing the java code here but error occur

public static void main(String[] args) throws Exception{
    InputStream is = JsonParsing.class.getResourceAsStream( "");
    String jsonTxt = IOUtils.toString( is );
    JSONObject json = (JSONObject)JSONSerializer.toJSON(jsonTxt);   
    JSONObject html_attribution = json.getJSONObject(“html_attribution");
    JSONObject geometry= json.getJSONObject(“geometry”);
    JSONObject location= json.getJSONObject(“location”);

    double latitude = json.getDouble("latitude");
    double longitude = json.getDouble("longitude");
    String icon= result.getString("icon");
    String id = result.getString("id");
    String reference= result.getString("reference");
    String name = result.getString("name");
    String vicinity = result.getstring("vicinity");

    System.out.println("html_attribution: " + html_attribution);
    System.out.println("location: " + location);
    System.out.println(“latitude: “ + latitude);
    System.out.println(“latitu开发者_JAVA技巧de: “ + longitude);
    System.out.println("result: " + result);
}

I use the following:

http://code.google.com/p/google-gson/

Serialize to JSON:

Gson gson = new GsonBuilder().create(); 
String jsonOutput = gson.toJson(someObject);

De-serialize from JSON:

BagOfPrimitives obj = gson.fromJson(json, BagOfPrimitives.class);

A user guide can be found here:

Use a java library from http://www.json.org/.

---

Take a look at the GSON Google project. Its a library that lets you get all your JSON data into Java objects. Its quite simple.

JSONObject geometry = json.getJSONObject("geometry");

JSONObject location = json.getJSONObject("location");

String lat = location.getString("lat");
String lng = location.getString("lng");

icon = json.getString("icon");

id = json.getString("id");

name = json.getString("name");

reference = json.getString("reference");

vicinity = json.getString("vicinity");

JSOnArray types = json.getJSONArray("types");

for (int i=0;i<=types.length();i++)
{

JSonObject temJson = (JSONObject) types.get(i);

String Varialb = temJson.get(i);

}
