Ok does anyone know how to make one of those Java things where u choose a price range for lets say a car and it spits u out a few cars that match that range. Or maybe car types or something. I need to put something like that on a webpage im making for a person, and i dont know how to do it.

What do i have to use to do that? Do i make an applet or do i hook it up to a database or how do i approach this? Please help!
