程序员老黄历Java源码实现_老黄历源码js

今早起来，无聊之际把程序员老黄历用Java实现了一番。

原JS版地址：http://sandbox.runjs.cn/show/ydp3it7b/

尊重原作……哈哈哈(连备注都复制的人是不是很恶心的？)

代码如下：

今天是：今天是2016年9月25日 星期日
座位朝向：面向西方写程序，BUG 最少。
今日宜饮：可乐,果汁
女神亲近指数：★★☆☆☆
宜：
    锻炼一下身体
    晚上加班:晚上是程序员精神最好的时候
    浏览成人网站:重拾对生活的信心
不宜：
    打DOTA:你会被虐的很惨
    上AB站:满屏兄贵亮瞎你的眼
