Question

So I am trying to pull data from my database and essentially create a JSON file that looks like this. I know of that I can use my_json_object.put(); but that seems to only work for String, String. I and I want to create the value with 2 entries, and the second entryw ill actually be an array of many values. How can I achieve that? Thanks guys.

{"value": {
"name": "History",
"values": [ 
{"front": "History Market", "back": " It is the world of the world that the world    could not say that", "color": "Yellow"},
{"front": "History Market", "back": " It is the world of the world that the world could not say that", "color": "Red"},
{"front": "History Market", "back": " It is the world of the world that the world could not say that", "color": "Purple"},
{"front": "History Market", "back": " It is the world of the world that the world could not say that", "color": "Blue"},
{"front": "History Market", "back": " It is the world of the world that the world could not say that", "color": "Blue"}
]}}

Create your current jsonObject as :

//Create main json object
JSONObject json = new JSONObject();

//Create value json object
JSONObject valueJson = new JSONObject();

//Create values JSONArray
JSONArray valuesarray = new JSONArray();

for(int i=0;i<=4;i++){
 // Create values jsonObject
JSONObject valuesJson = new JSONObject();
valuesJson.put("front","front_value");
valuesJson.put("back","back_value");
valuesJson.put("color","color_value");
 // put values jsonObject to valuesarray JSONArray
valuesarray.put(valuesJson);    

}
 // put name key-value to value jsonObject
valueJson.put("name","History");
 // put values JSONArray to value jsonObject
valueJson.put("values",valuesarray);

 // put value jsonObject to final json Object
json.put("value",valueJson);
