c++ - Difference between final class and override final

Question

The question is pretty simple, what's the difference in using final like this,

class Base {
public:
    Base() {}
    virtual ~Base() {}

    virtual void Initialize() {}
};

class Derived final : public Base {
public:
    Derived() {}
    ~Derived() {}

    virtual void Initialize() override {}
};

And using override final like this,

class Base {
public:
    Base() {}
    virtual ~Base() {}

    virtual void Initialize() {}
};

class Derived : public Base {
public:
    Derived() {}
    ~Derived() {}

    virtual void Initialize() override final {}
};

Answer 1

The first case locks the class. The following would cause an error:

class Derived2 : public Derived{};

The second forbids any class that inherits from it to redefine the finalmethod.
