线程状态

     * 线程状态
     *     操作系统五种：
     *     初始状态
     *     可运行状态
     *     运行状态
     *     阻塞状态 阻塞的io操作
     *     终止状态
     *
     *  线程六种状态
     *    NEW
     *    RUNNABLE 涵盖操作系统的运行，可运行，阻塞 调用阻塞api状态
     *    BLOCKED  没有获取到锁
     *    WAITING   调用join
     *    TIMED_WAITING  join（timeOut）
     *    TERMINATED
