4.2 Override
When using inheritance, always use the appropriate keyword to mark that a function is overriding another function.
Use the @Override annotation when overriding a function.
Always make sure to call the super version of the function unless the documentation explicitly says otherwise.
Mark functions you want overridden as virtual. Make sure the proper visibility is used IE protected or public.
When overriding functions, always include the override or final keyword so the compiler can raise errors if you use the wrong function signature.
If your class contains any virtual functions, make sure to declare the destructor virtual as well.
If you don't want a function to be overridden, use the final keyword on the class or function.
