Answer 3

Answer 4

Private variables or methods can be accessed only from the methods of the class to which it belongs. A subclass also does not have access to the private variables.

Answer 5

Private allows functions and variables of a class to only be used within that class. For security/dev team use. Protected allows only that class and its derived classes use them but they will not appear when just making the object type as a variable somewhere for use. And finally, public is used to give access everywhere. You can also use private, protected, and public when enheritting from another class and this determines how the public/protected variables and functions are brought in to the current class, even if their access keyword is more accessible

Answer 6
