本文實(shí)例為大家分享了java實(shí)現(xiàn)停車場系統(tǒng)的具體代碼，供大家參考，具體內(nèi)容如下

現(xiàn)開發(fā)一個停車系統(tǒng)，用戶根據(jù)車位停車

1)車主查看現(xiàn)在有無車位(最多100個車位),給車主隨機(jī)分配一個車位,如果該位置上有車,不能停2)按停車時間收費(fèi),3小時以內(nèi)不收費(fèi),3小時以外,每小時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)
