Train()。((1))。((2))。((3))。((4))。((5))。((6))。((7))。((8))。((9))。((10))。((11))。((12))。((13))。((14))。(train)。} } catch(SQLException e){()。}finally{(rs)。(pt)。(con)。}return list。} 其中的update的功能是，首先連接數(shù)據(jù)庫，然后用傳遞過來的SQl語句在列表中刪除某輛列車的信息。getAllTrain（）方法是顯示所有的列車的信息。圖示如下：武漢理工大學(xué)《軟件開發(fā)工具》論文報告 來實現(xiàn)的。代碼如下：import 。import .*。import .*。import .*。import 。public class
