[Java] 自己写了个随机抽签器

制定随机主题日，强迫自己写不同寻常的内容 #生活技巧# #创意技巧# #写作创意灵感#

上网上找了半天, 没一个满意的, 干脆自己捣腾着做了一个. 

界面比较简单,不过使用还是比较方便的.

说明:
document.txt 中添加/删除 抽签的条目, 每行一个条目,可输入数字作为随机抽奖器用, 也可输入人名当随机点名器用.

propert.ini 可修改配置
fontFamily : 设置字体
fontSize : 设置字体大小(20~100)
fontWeight : 设置字体粗细(0~1), 默认0
width : 设置窗口宽度(600~MAX), 默认600, MAX屏幕大小
height : 设置窗口高度(400~MAX), 默认400 
amortize : 设置缓冲次数(1~30), 默认25

贴上源码, 求大神指点
这是读取配置的
