Statement stmt = Conn.createstatement ();
ResultSet rs = stmt.executequery ("Select * from Stu"); Get the records in the Stu table
Out.println ("table-list" + "<br>");
while (Rs.next ()) {
Out.print (Rs.getint (1) + "");
Out.print (rs.getstring (2) + "<br>");
}
Rs.close ();
Stmt.close ();
Conn.close ();
}
