Protected access modifiers allow the data members to be accessed by class, package, subclass (same package), subclass (different package). The difference between public and protected is that public can be accessed from outside class but protected cannot be accessed from outside class.

What is the difference between protected and private methods?

The private modifier specifies that the member can only be accessed in its own class. The protected modifier specifies that the member can only be accessed within its own package (as with package-private) and, in addition, by a subclass of its class in another package.

What is the difference between private and public and protected in unity?

What is private vs protected vs public inheritance?

With public inheritance, the derived class can see public and protected members of the base. With private inheritance, it can't. With protected, the derived class and any classes derived from that can see them.

What is the term for public private?

A public–private partnership (PPP, 3P, or P3) is a long-term arrangement between a government and private sector institutions. Typically, it involves private capital financing government projects and services up-front, and then drawing revenues from taxpayers and/or users for profit over the course of the PPP contract.

Why protected instead of private?

- Private data members cannot be accessed outside the class. - When a class inherits a base class, all the data members except the private get inherited into it. So if we want data members to be accessible to only derived classes and not privately or publicly accessible, then we can use protected.

What information is legally protected?

The Privacy Act of 1974, as amended to present, including Statutory Notes (5 U.S.C. 552a), Protects records about individuals retrieved by personal identifiers such as a name, social security number, or other identifying number or symbol.

What is the difference between privacy and protection?

Both are needed to ensure that data remains secure. Another important distinction between privacy and protection is who is typically in control.

Can protected members be accessed by objects?

Protected members that are also declared as static are accessible to any friend or member function of a derived class. Protected members that are not declared as static are accessible to friends and member functions in a derived class only through a pointer to, reference to, or object of the derived class.

What is the point of private inheritance?

Private Inheritance is one of the ways of implementing the has-a relationship. With private inheritance, public and protected member of the base class become private members of the derived class. That means the methods of the base class do not become the public interface of the derived object.

What is an example of a private inheritance?

Suppose, a parent gave a child a secret recipe for a candy under the condition of not releasing the recipe. The child can give variety of candies to other people but not the recipe. With private inheritance, the derived class does enjoy(implement) the inherited interface but does not own the method.

Should I use private or protected?

Private members make the code cleaner, more readable, and highly maintainable. This is so because the private attributes and methods are confined to the defining class so we document them there. However, protected entities have to be documented at all places where we override them.

Which is more secure private or protected?

If you are going to use the functions everywhere in the program you should use public. If you want to use them only when they are needed by the classes that extends that class you have to use protected. If you want to use it only inside that class you should use private. This largely depends on context.

What is meant by protected visibility?

In the protected visibility mode, when we inherit a child class from the parent class, then all the members of the base class will become the protected members of the derived class. Because of this, these members are now only accessible by the derived class and its member functions.

When should we use protected?

If you want to allow access from subclasses or classes within the same package, 'protected' is a good choice. If you want to allow access from any class in the same package, consider using 'default'. And if you want to allow unrestricted access, 'public' is the best choice.

Can you override protected to public?

Yes, the protected method of a superclass can be overridden by a subclass. If the superclass method is protected, the subclass overridden method can have protected or public (but not default or private) which means the subclass overridden method can not have a weaker access specifier.

What are the three types of privacy?
