投票管理系統(tǒng)

1、投票管理系統(tǒng)1 題目描述投票選舉過程：（1）用戶從鍵盤輸入候選人的個數(shù)（提示用戶輸入人數(shù)為1-12）、當(dāng)選標(biāo)準(zhǔn)（例：若為50%，只需輸入50即可）。點(diǎn)擊確定后，由用戶從鍵盤輸入每一個候選人的姓名，提交后即可生成候選人的信息（包括姓名和編號）。（2）投票者就開始投票，對投票者沒有姓名和編號的存儲，只有結(jié)果的存儲。（3）以表格的形式展示選舉結(jié)果，包括：候選者的編號、姓名、所得票數(shù)、得票率、是否中選，并附投票人的個數(shù)和當(dāng)選標(biāo)準(zhǔn)。2類設(shè)計(jì)2.1 類圖Manager：控制整個系統(tǒng)，并對投票結(jié)果以及是否當(dāng)選進(jìn)行控制；UserInterface：控制整個系統(tǒng)的展示；MainGraph：接收候選者人數(shù)、姓名、

2、當(dāng)選標(biāo)準(zhǔn)信息；VoteGraph：接受用戶的投票信息；ResultGraph：展示最終的投票結(jié)果；Candidate：候選人的實(shí)體對象，包括候選人的各種屬性；2.2 類聲明本報(bào)告采用java編程語言，一共構(gòu)造了六個類：1、Candidate; 2、Manager； 3、UserInterface；4、MainGraph；5、VoteGraph ；6、ResultGraph。2.2.1、候選者類：Candidatepublic class Candidate private String name;/候選者姓名private int id;/候選者的編號private int num; / 得票

9、假若依次輸入12， 50.點(diǎn)擊確定后，窗口中會提示輸入侯選人的姓名，候選人的編號是從小到大依次生成的。依次輸入12人的姓名點(diǎn)擊提交后，就會彈出投票的窗口假若共有7名投票人參與投票（每次投票完點(diǎn)擊提交即為完成依次投票）投票過程如下：投票者1：1號：吳紅巖 3號：邵芳 9號：李丹 11號：李四投票者2：2號：劉莉莉 3號：邵芳 4號：尹聰敏 6號：王小麗8號：王永霞 投票者3：1號：吳紅巖 2號：劉莉莉 4號：尹聰敏 5號：張三7號：李澤 9號：李丹投票者4：1號：吳紅巖 7號：李澤 12號：王龍賀 投票者5：3號：邵芳 4號：尹聰敏 5號：張三 7號：李澤10號：王小慧投票者6：1號：吳紅巖 2
