Thanks for the PR.
Some points,

1. IMHO, we should use, DynamicOneDimensionalArray for self.queue(which I think can be renamed as self.items).
2. Is Queue a double ended queue?
3. IMHO, we can remove size as an argument for initialising as DynamicOneDimensionalArray is capable of handling variable sizes.

See, current implementation of stacks. We can have similar design for Queue as well. An ArrayQueue for array implementation.
