convert them both to a numerical data type and then add them together.
Very easy.

hi

i mean i knw how to calculate and convert to int. But if put the total in a variable. then how would i retrive it in servlet and save it in the database?

thanks

you'd have to send it to the servlet, the servlet isn't going to know it's there to be saved unless someone tells it so.

how would i send it to servlet is it the action attribute.... or something else? because the variable total wouldnt be shown to users..

As a request attribute, or a session attribute, doesn't really matter.
