Raja,

If you look at the source code, you can see, apart from the differences that you have mentioned, the capacity increment ratio of Vector and ArrayList are different as well. I think Vector's capacity doubles every time its size reaches its capacity, whereas ArrayList's capacity increase by a factor of 1.1 (or something similar).

btw, if that is not confidential, with which company did you have the interviews?

Cheers,

Tim.
