how do i retrieve my arraylist into html table?

my arraylist: 

[
1, 2011-05-10,  1,  22.0, 
2, 2011-05-10,  2,  5555.0, 
3, 2011-05-11,  3,  123.0, 
4, 2011-05-11,  2, 212.0, 
5, 2011-05-30,  1,  3000.0, 
6, 2011-05-30,  1,  30.0, 
7, 2011-06-06,  1,  307.0, 
8, 2011-06-06,  1,  307.0 ]

out.println("<html>");
        out.println("<head>");
        out.println("<title>Counter</title>");
        out.println("</head>");
        out.println("<body>");
        out.println("<table border=\"1\">");
        out.println("<tr>");
        for (int i = 0; i < ex.getExpenses().size(); i++) {
            out.println("<td>" + ex.getExpenses().get(i) + "</td>");

            if (i>0 && i%4==0) {
                out.println("</tr><tr>");

            }

        }
        out.println("</tr>");
        out.println("</table>");
        out.println("</body>");
        out.println("</html>");

this doesn’t really work, since arraylist starts with 0, it gives me the table that looks like this: enter image description here

how do i get the table that looks like this: 

1 2011-05-10  1  22.0
2 2011-05-10  2  5555.0 
3 2011-05-11  3  123.0 
4 2011-05-11  2  212.0 
5 2011-05-30  1  3000.0
6 2011-05-30  1  30.0
7 2011-06-06  1  307.0
8 2011-06-06  1  307.0

    Replace

        for (int i = 0; i < ex.getExpenses().size(); i++) {
        out.println("<td>" + ex.getExpenses().get(i) + "</td>");
        if (i>0 && i%4==0) {
            out.println("</tr><tr>");
        }
    }

    with

        for (int i = 0; i < ex.getExpenses().size(); i++) {
        if (i>0 && i%4==0) {
            out.println("</tr><tr>");
        }
        out.println("<td>" + ex.getExpenses().get(i) + "</td>");
    }

    By the way. Create separate class Expenses that contains 4 fields. It will be much cleaner and easier to convert this to html. You can write special separate method for converting Expenses to html table row.
