Learning classical isn't bad, there's quite a lot in there which you can use for other styles as well. Just don't let it stay there if you want to learn other stuff, and do not let your teacher decide too much about what you should learn, you may end up hating the instrument that way.
Should your teacher refuse to teach you anything else than classical, then there's a lot of experienced people here to help you out with anything you may want to know.
