Java oop：人類抽象類，抽象方法，接口，集合，登錄，普通員工管理系統(tǒng)
//作業(yè):
//聲明人類抽象類，包含人類名稱，性別，年齡，普通工作時(shí)長，開會時(shí)長和一個(gè)抽象方法（用于計(jì)算總時(shí)長
//（普通工作時(shí)長+開會時(shí)長）方法），
//再聲明一個(gè)地區(qū)的接口，聲明子類普通員工繼承人類抽象類人類和實(shí)現(xiàn)抽象方法
//（打印出同一個(gè)地區(qū))，
//再分別實(shí)例化5個(gè)人放入到集合中，制作登錄案例，登錄成功后跳入功能界面，功能分4個(gè)：
//1.查詢所有的人的信息? ?2.修改某個(gè)編號員工的性別和年齡
//3.查詢某個(gè)員工的信息? ? 4.退出系統(tǒng)
