停車場停車系統(tǒng)太差勁！看我用Java手?jǐn)]一個(gè)停車場系統(tǒng)！
來源：blog.csdn.net/weixin_43951778
現(xiàn)開發(fā)一個(gè)停車系統(tǒng),用戶根據(jù)車位停車，主要實(shí)現(xiàn)以下4個(gè)常用功能：
1)車主查看現(xiàn)在有無車位(最多100個(gè)車位),給車主隨機(jī)分配一個(gè)車位,如果該位置上有車,不能停
2)按停車時(shí)間收費(fèi),3小時(shí)以內(nèi)不收費(fèi),3小時(shí)以外,每小時(shí)2元,最大20元
3)車主可以查看自己停車的車位和收費(fèi),以及停車的時(shí)長
4)查看歷史停車記錄
管理員:
查看現(xiàn)有的剩余車位
查看已停車的車位
查看停在車位上的車以及歷史繳費(fèi)
