Cannot properly parse and display Json

while((inputLine = in.readLine()) != null)
{
	jsonData = inputLine;
	System.out.println(jsonData);
	
}

JSONObject object = null;
try {
	object = (JSONObject) new JSONParser().parse(jsonData);
} catch (ParseException e) {
	// TODO Auto-generated catch block
	e.printStackTrace();
}
JSONObject weather = (JSONObject) object.get("weather");
String description = weather.get("description").toString();

System.out.println(description);
		
in.close();

The above code produces the following error:

The code I've attached starts at line 38. I want to try to print out the "description" field from the Json I have parsed.

The relevant part from the json is:

"weather": [ { "id": 800, "main": "Clear", "description": "clear sky", "icon": "01n" } ],

You are Parsing a JSONArray to JsonObject
at below line in ur code

JSONObject weather = (JSONObject) object.get("weather");

weather is a JsonArray
I tried below code it worked for me.

    public static void main(String[] args) {
       JSONObject jsonObject = new JSONObject("{\"weather\": [ { \"id\": 800, \"main\": \"Clear\", \"description\": \"clear sky\", \"icon\": \"01n\" } ]}");
       JSONArray weatherArray = jsonObject.getJSONArray("weather");
       JSONObject weatherJson = weatherArray.getJSONObject(0);
       System.out.println(weatherJson.get("description"));
    }

output

clear sky
