ArrayList method in JSP

Question

I tried to create arrayList method in JSP as the following :

    <%!
       public int x = 0;
       public ArrayList array = new ArrayList();
       array.add(new ArrayList());
       public ArrayList cidTime (int cid, int w)
       {
            ((ArrayList)array.get(x)).add(cid);
            ((ArrayList)array.get(x)).add(w);
            x++;
            return array;
       }
      %>

but it returned error :

                    Syntax error on token(s), misplaced construct(s) 
                    Syntax error on token "add", = expected after this token

any suggestion?

Don't put Java code in your JSP pages, see http://stackoverflow.com/a/3180202/249327 for many reasons why. Do that in your controller or else create a taglib and put the code there. — nickdos, Nov 15 '12 at 05:25

Learn basic Java first before switching to JSP. This ain't JSP problem — Hardik Mishra, Nov 15 '12 at 05:29
@nickdos: ok, thanks. I will follow your suggestion. Thanks, anyway. — Doni Andri Cahyono, Nov 15 '12 at 05:45

You are using JSP declaration tag <%!. According to the info here it places declarations and methods outside the service method body of the JSP page. Which means that your call array.add(new ArrayList()); is causing the problem because it is not variable declaration or method declaration.
