/*
*此小程序的基本流程是，在一個(gè)文本文件存放里面?zhèn)溥x的數(shù)據(jù)，數(shù)據(jù)的格式是每行有姓名 和 手機(jī)號(hào)
*他們之間是用分隔符-來分隔的。然后在自定義一個(gè)方法，通過分隔符來區(qū)分姓名和手機(jī)號(hào)，然后將
*他們分別存儲(chǔ)進(jìn)兩個(gè)不同的可變向量當(dāng)中。
*   自定義一個(gè)線程，此線程是專門用來隨機(jī)選取一個(gè)號(hào)碼， 并且每隔50毫秒就將一個(gè)不同的號(hào)碼顯示在
*   號(hào)碼框中，這樣就實(shí)現(xiàn)了號(hào)碼的快速滾動(dòng)，實(shí)現(xiàn)了完全模擬電視當(dāng)中抽獎(jiǎng)的畫面
* 
*   為了實(shí)現(xiàn)選取出的一個(gè)號(hào)碼不能再被選種，實(shí)現(xiàn)的方法是將他們從可變向量中清除出去
* 
*   本程序的數(shù)據(jù)來源選用的是文本文件，原因有，第一，這是一個(gè)小程序，加上數(shù)據(jù)庫顯得不適宜。第二，本著
*   學(xué)習(xí)的態(tài)度，因?yàn)?，如果用?shù)據(jù)庫來實(shí)現(xiàn)的話，很多功能都可以通過sql語句和 數(shù)據(jù)庫的功能來實(shí)現(xiàn)。而此程序
*   所有的功能都需程序本身來承擔(dān)完成。當(dāng)然，對(duì)于有大量的數(shù)據(jù)來說，還是需要數(shù)據(jù)庫的。像這樣把數(shù)據(jù)一次性
*   讀入內(nèi)存中，大于大量數(shù)據(jù)是不行的！
* 
*   此程序是在無界面設(shè)計(jì)的環(huán)境eclipse下設(shè)計(jì)完成的，界面難免顯得僵硬....
* 
*   在以后的版本中還將實(shí)現(xiàn)，用戶可以自己設(shè)定 名額，獎(jiǎng)項(xiàng)等....
