3、 系統(tǒng)總體設計成功登陸系統(tǒng)以后，出現(xiàn)成績管理界面，系統(tǒng)初始化，可對學生成績進行增加、刪除、查詢、修改、統(tǒng)計，進入相應界面進行成績管理，退出系統(tǒng)自動保存本次操作容，保存信息。簡易流程圖： 登陸成績管理界面增加刪除查詢修改統(tǒng)計退出3 系統(tǒng)詳細設計創(chuàng)建Student類，設置變量及對應方法Student.java代碼：package keshe;import java.io.Serializable;publicclassStudentimplements Serializableprivate String name;privateintnum;privateintyuwen;privateints
