Convert a json array to an hashmap<string,object>

I have an external parsed List type which is a json array, indeed this call

list.toString()

gives me this:

[{name=prop1, content=<something>},{name=prop2, content=<something>}]

The content could be anything, an array, a string, an int... So I'd like to map that json array to something like

HashMap<String,Object> converted;

This would allow me to do this:

converted.get("prop1"); //this will give me the <something>

how could I do that?

Try this using JSON Parser. Get the JSON lib from here json.simple

Map<String, Object> map = new HashMap<>();

JSONParser parser = new JSONParser();

try {

  Object obj = parser.parse(list);

  JSONArray jsonArray = (JSONArray)obj;

  Iterator<JSONObject> iterator = jsonArray.iterator();
  while (iterator.hasNext()) {
       JSONObject jsonObj = iterator.next();
      String name = (String) jsonObject.get("name");
       Object content = (Object) jsonObject.get("content");
       map.put(name, content);
  }
} catch (ParseException p) { }
