[java] Convert JSONObject to Map

This is what worked for me:

    public static Map<String, Object> toMap(JSONObject jsonobj)  throws JSONException {
        Map<String, Object> map = new HashMap<String, Object>();
        Iterator<String> keys = jsonobj.keys();
        while(keys.hasNext()) {
            String key = keys.next();
            Object value = jsonobj.get(key);
            if (value instanceof JSONArray) {
                value = toList((JSONArray) value);
            } else if (value instanceof JSONObject) {
                value = toMap((JSONObject) value);
            }   
            map.put(key, value);
        }   return map;
    }

    public static List<Object> toList(JSONArray array) throws JSONException {
        List<Object> list = new ArrayList<Object>();
        for(int i = 0; i < array.length(); i++) {
            Object value = array.get(i);
            if (value instanceof JSONArray) {
                value = toList((JSONArray) value);
            }
            else if (value instanceof JSONObject) {
                value = toMap((JSONObject) value);
            }
            list.add(value);
        }   return list;
}

Most of this is from this question: How to convert JSONObject to new Map for all its keys using iterator java
