31、是否存在，如果存在則輸出對應的學生信息，否則提示沒有這個學生的存在，進入是否繼續查找學生信息?是（y/Y）否（n/N）操作；輸入“3”時進入執行更新學員的基本信息操作，adminStu.print(stuArr) 輸出所有學生信息，輸入學號進行查詢，adminStu.update(num, newNum, newName, newAge, newOrigin, newTime, newAcademy, stuArr)更新學生基本信息，更改完后將學生信息輸出顯示。輸入“4”執行刪除學生操作，先輸出顯示所有學生信息，再按照提示輸入要刪除的學號，是（y/Y）否（n/N）確認刪除，adminStu.d
