Answer 1

Here i have written a simple function with recursion:

public static JSONObject replaceAll(JSONObject json, String key, String newValue) throws JSONException {
    Iterator keys = json.keys();
    while (keys.hasNext()) {
        String k = (String) keys.next();
        if (key.equals(k)) {
            json.put(key, newValue);
        }
        Object value = json.opt(k);
        if (value != null && value instanceof JSONObject) {
            replaceAll((JSONObject) value, key, newValue);
        }
    }
    return json;
}
