Depends on the leaf formation but it could be a hickory. I don't believe pecan would fruit in NJ.

get some pics!

hazelnuts are much more shrubby in stature than hickories. if it's a sizeable tree, it's not hazelnut.

Do any of these look like what you have? Compare the leaves, as well as the unripe nuts.

I was thinking walnuts. Pics would be a big help. I agree with Bullthistle, it is unlikely that pecans would fruit in South Jersey but it might be possible over near the shore where the zone is a 7b. English walnuts will tend to have an eliptical fruit but the bark is light colored. lackwal nuts fruit starts out as an eliptical shape then rounds out as it matures and has a dark colored bark. may be a hickory, ther are maybe a half dozed different hickories that might be found in NJ, each with a rather individual nut and quite a range of bark patterns.
