Answer by lewis machilika for Loop through nested JSON array

You may try

        public void printJsonObject(JSONObject jsonObj) {            for (String keyStr : jsonObj.keySet()) {                Object keyvalue = jsonObj.get(keyStr);                //Print key and value                System.out.println("key: "+ keyStr +" value: " + keyvalue);                //for nested objects iteration if required                if (keyvalue instanceof JSONObject)                    printJsonObject((JSONObject)keyvalue);            }        }
