请帮帮我。这是我第一次问这里:(谢谢..

1 个答案:

答案 0 :(得分：1)

您的问题出现在此部分代码中：

connection c = new connection();
DefaultTableModel T;
T= c.returndata("Select * From medrec Where student_no=?");

具体是第3行。如果您打开connection类（您没有显示代码）并找到方法returndata，您应该看到它将具有以下代码行：

throw new UnsupportedOperationException("Not supported yet");

这告诉您没有提供执行此方法所需的代码。
