AsyncTask类VS AsyncTask对象

Question

无法找到以下哪种使用AsyncTask技术更好（性能明智，内存管理，设计明智）的问题的答案？

对象示例

class AsyncTaskObjectExample {

    protected AsyncTask<String, Integer, Boolean> asyncTaskObject = new AsyncTask<String, Integer, Boolean>() {
        @Override
        protected Boolean doInBackground(String... params) {
            /* YOUR PROCESSES */
            return true;
        }
    };
}

课程示例

class AsyncTaskClassExample {

    class AsyncTaskClass extends AsyncTask<String, Integer, Boolean> {
        @Override
        protected Boolean doInBackground(String... params) {
            /* YOUR PROCESSES */
            return true;
        }
    }
}
