Java code to alternate row bgcolors

Question

Hey all,
I have a table that's size is dynamic depending on the size of a resultset returned from the database. I want to pretty up the table by alternating the color of the rows. I was able to do this in asp by using the mod fuction which returns the remainder of an integer, and so if i = 1 bgcolor=white, if i=2 bgcolor=gray. I'm not sure what to use in jsp. Take a look at my code, and see if you know of a better way.
<%
    int rowcount = 0;
    String rowbgcolor = "";
    int i = 1;
    while(i <= validUsers.length){
        rowcount = rowcount + 1
        if rowcount mod 2 = 0 then
                rowbgcolor = "#F8F8B1"
        else
                rowbgcolor = "#ECEC88"
        end if
        %>
        <tr bgcolor="<%=rowbgcolor%>">
            <td><img src="<bean:message key="marsapp.images_dir"/>/icon_edit.png" /> </td>
            <td><%=validUsers.getUsername()%> </td>
<td><%=validUsers[i].getLastname()%>, <%=validUsers[i].getFirstname()%> </td>
<td><%=validUsers[i].getPhone()%> </td>
<td><%=validUsers[i].getFax()%> </td>
</tr>
<%i++;
%>
There is probably an easier way to do this with css but I'm no whiz with that. This is a struts application, but I dont find struts to be useful when generating formated tables like this. Is there something that I'm missing or is this already built into struts?

Answer 1

sorry for not giving anyone a chance to reply, but here is the code transferred to jsp. It has the desirable effect of alternating rows, but it looks a bit sloppy to me. Still looking for suggestions for a better way.
<%
mars.UserDAO currentDAO = (mars.UserDAO)session.getAttribute("UserDAO");
mars.User[] validUsers = currentDAO.getUsers();
%>
<table cellspacing="0" cellpadding="2" width=600 align="center">
    <tr class="TableRowHeader" bgcolor='#ECEC88'>
        <td> </td>
        <td>Username</td>
        <td>Name (Last, First)</td>
        <td>Phone</td>
        <td>Fax</td>
    </tr>
    <%
    String rowbgcolor = "";
    int i = 0;
    while(i <= validUsers.length-1){
        if ((i % 2) == 0){
                rowbgcolor = "#F8F8B1";
        else{
                rowbgcolor = "#ECEC88";
        }%>
        <tr bgcolor="<%=rowbgcolor%>">
            <td><img src="<bean:message key="marsapp.images_dir"/>/icon_edit.png" /> </td>
            <td><%=validUsers.getUsername()%> </td>
<td><%=validUsers[i].getLastname()%>, <%=validUsers[i].getFirstname()%> </td>
<td><%=validUsers[i].getPhone()%> </td>
<td><%=validUsers[i].getFax()%> </td>
</tr>
<%i++;
}%>
