/*
*此小程序的基本流程是,在一个文本文件存放里面备选的数据,数据的格式是每行有姓名 和 手机号
*他们之间是用分隔符-来分隔的。然后在自定义一个方法,通过分隔符来区分姓名和手机号,然后将
*他们分别存储进两个不同的可变向量当中。
*   自定义一个线程,此线程是专门用来随机选取一个号码, 并且每隔50毫秒就将一个不同的号码显示在
*   号码框中,这样就实现了号码的快速滚动,实现了完全模拟电视当中抽奖的画面

*   为了实现选取出的一个号码不能再被选种,实现的方法是将他们从可变向量中清除出去

*   本程序的数据来源选用的是文本文件,原因有,第一,这是一个小程序,加上数据库显得不适宜。第二,本着
*   学习的态度,因为,如果用数据库来实现的话,很多功能都可以通过sql语句和 数据库的功能来实现。而此程序
*   所有的功能都需程序本身来承担完成。当然,对于有大量的数据来说,还是需要数据库的。像这样把数据一次性
*   读入内存中,大于大量数据是不行的!

*   此程序是在无界面设计的环境eclipse下设计完成的,界面难免显得僵硬....

*   在以后的版本中还将实现,用户可以自己设定 名额,奖项等....
