getParameterMap and unselected checkboxes

I'm processing information from a form in a servlet that consists of a table of data, each with a checkbox. Some are selected, and others are not. When I user getParameterMap() or getParameterNames(), I'm only getting data for those rows that have the checkbox selected (true).
How do I also get the checkboxes that are no selected?

You don't. Parameters for unselected checkboxes are not included in the HTTP request when the browser submits the form.

As Bear said, only selected parameters are sent as part of the request. But, since you know those that are selected, you can easily detemine those that are not right?
