Which code does not contain errors?

typedef int Type;
template <class Type>
class Class {
    ...
    public:
    Type val;
}

template <class Type>
class Class {
    ...
    public:
        typedef int Type;
        Type val;
}

In this case:

typedef int Type;
template <class Type>
class Class {
    ...
    public:
    Type val;
}

the declared template parameter names hide the names in the global space.
