How can use ' Vector ' in JSP

Question

I use rs.getString(1); can get three strings like "12:00-13:00", "01:00-02:00", "02:00-03:00" from sql 2000. I would like these time one by one, if it equals user select. System will show the message...then I use following code...but doesn't work because jsp said Vector not a type.(cannot resolve).... I would like to know any other methods can do the same things. hope sb help... thank you
Vector stringVector = new Vector();
while(rs.next()){
stringVector.addElement(rs.getString(1));
Iterator sv = stringVector.iterator();
while (sv.hasNext()){
if(time.equals((String)sv.next())
out.println("wrong");
else{
......

I personally would use an ArrayList. From what I hear, it's better than a vector. You want to make sure that you include the line at the top
<%@ page import = "java.util.ArrayList" %>
ArrayList stringVector = new ArrayList ();
while(rs.next()){
stringVector.add(rs.getString(1));
for (int i =0; i < stringVector.size(); i++){
   if(time.equals((String)stringVector.get(i))
   out.println("wrong");
else{No need to bother with any of that iterator stuff. My guess is that you're not including the Vector below, or a required jar file is missing (but Vector is part of the core java package, so the file can't be missing)
