THE SEVENTEENTH DAY

    今天星期天，参加培训的第十七天，早上有点不想起床，一直到七点才起来，挺纠结的，很累，可能是游戏来去玩多了，其余的也没有什么，嗯早上也没有吃饭，反正就是很懒就对了，然后早上来了，看了一会书，补了一下昨天的日记，然后继续看书，有一个居中显示文字的代码，还有一个显示时钟的代码，感觉还好吧，其它的也没有什么，反正是看的不多，一上午就过去了，也不知道到底做了些什么，唉，很纠结。
    中午，吃了饭，回来小睡了一会，然后，老师带着串了一下学过的知识，然后就下课了，到现在，我在写今天的日记，不知道该做什么了，脑袋有点晕晕的，什么也不想做，也好，那就什么也不做好了，要不然呢，对吧，好的，不说什么有的没的了，就先这样吧，毕竟实在是提不起干劲来。

    贴一下今天的代码吧，凑一下今天的字数，行，就这样。

  居中文字代码：package graphics;

  好了，别的也没有什么了，要不然呢，哈哈，没有什么意思，结束了，好，结束。
    不对，还有一件好玩的事情没有说，是这样的，今天，有人评论了我的日记，感觉惊呆了，还对我表示感谢呢，有什么值的借鉴的吗，说出来，我也借鉴一下，哈哈，挺好的，还蛮高兴的，毕竟有人感谢了我，虽然我也不知道哪里有值得借鉴的地方，算了，别的没有什么了，好了，结束 。
