Following is the code to parse a json string
import java.util.Iterator; import org.json.JSONArray; import org.json.JSONException; import org.json.JSONObject; public class TestJson1{ private static String jsonStr = ""; public static void main(String[] args){ try{ JSONObject obj = new JSONObject(jsonStr); parseJson("", obj); } catch(Exception e){ e.printStackTrace(); } } public static void parseJson(String key, JSONObject jsonObject){ try{ Iterator iterator = jsonObject.keys(); while(iterator.hasNext()){ String obj = iterator.next().toString(); String keyVal = (key.equals("")) ? obj : key + "." + obj; if(jsonObject.get(obj) instanceof JSONArray){ JSONArray jsonArr = (JSONArray) jsonObject.get(obj); for(int k=0; k < jsonArr.length; k++){ if(jsonArr.get(k) instanceof JSONObject){ parseJson(keyVal + "[" + k + "]", (JSONObject) jsonArr.get(k)); } else{ System.out.println(keyVal + " :: " + jsonArr.get(k)); } } } else{ if(jsonObject.get(obj) instanceof JSONObject){ parseJson(keyVal, (JSONObject) jsonObject.get(obj)); } else{ System.out.println(keyVal + " :: " + jsonObject.get(obj)); } } } } catch(Exception e){ e.printStackTrace(); } } }
