Review Comment:
Here, by adding member variables, these two parameters can be passed in
through different constructors. For functions that do not require null
checking, use the default constructor. For scenarios that require null checking
or allow cast, it will be more versatile to pass them in through different
constructors.
So we can create various ArrayElementOperandTypeChecker instance. what do
you think?
