How to save LinkedHashMap binding in JSONObject?

Question

I have LinkedHashMapwith conditions.

Map<String, String> stateMap = new LinkedHashMap<String, String>();
// ...

I create on it JSONObject.

JSONObject json = new JSONObject();
json.putAll(stateMap);

However, the entries look disordered. I would like to keep ordering LinkedHashMapin JSONObject. How can I achieve this?

Answer 1

In contrast JSONObject, JSONArrayan ordered sequence of values. Therefore, if you want to keep the order of your map, you can create your object jsonwith two keys:

• The first key can be called data and will contain your data stateMapas follows:

  json.element('data', stateMap)
  

• , JSONArray, :

  JSONArray array = new JSONArray();
  array.addAll(stateMap.keySet())
  json.put('keys', array)
  

:

• JSONArray
• JSONObject
