You should put it like this
if (request.getParameter("modify") != NULL)
{
if (request.getParameter("modify").equals("yes") {
< your action here >
} else {
< your action here >
}
} else {
< your action if the parameter is empty here >
}
Otherwise you can end up with a NullPointerException from reading a NULL
parameter.
