> [Java] Provide a flag to enable/disable null-checking in vectors' get methods

> For vector classes, the get method first checks if the value at the given
> index is null. If it is not null, the method goes ahead to retrieve the
> value.
> For some scenarios, the first check is redundant, because the application
> code has already checked the null, before calling the get method. This
> redundant check may have non-trivial performance overheads.
> So we add a flag to enable/disable the null checking, so the user can set the
> flag according to their own specific scenario.
