    String jsonString = yourstring;
    JSONObject jsonResult = new JSONObject(jsonString);
    JSONArray data = jsonResult.getJSONArray("data");
    if(data != null) {
        String[] names = new String[data.length()];
        String[] birthdays = new String[data.length()];
        for(int i = 0 ; i < data.length() ; i++) {
            birthdays[i] = data.getString("birthday");
            names[i] = data.getString("name");
        }
    }

    Edit your code like this ...this may help you..

    JSONObject resultObject = new JSONObject(response);
    
    JSONArray JArray = resultObject.getJSONArray("data");
    
                    for (int t=0; t<JArray.length(); t++) {
    
                        JSONObject JObject = JtArray.getJSONObject(t);
    
    
    
    builder.append(JObject.getString("uid")+": ");

    In java, It's solved as

    String jsonString = yourstring;
    JSONObject data = JSON.parse(jsonString);
    
    //reading data using index
    long firstData_uid = data["data"][0]["uid"];
    String firstData_birthday = data["data"][0]["birthday"];
    String firstData_name = data["data"][0]["name"];
    

    In javascript, It's solved as

    var jsonString = yourstring;
    var data = JSON.parse(jsonString);
    
    //reading data using index
    var firstData_uid = data["data"][0]["uid"];
    var firstData_birthday = data["data"][0]["birthday"];
    var firstData_name = data["data"][0]["name"];
