Protected members in a class are similar to private members as they cannot be accessed from outside the class. But they can be accessed by derived classes or child classes while private members cannot.
How can a protected member be accessed in Java?
The methods or data members declared as protected can be accessed from:
- Within the same class.
- Subclasses of same packages.
- Different classes of same packages.
- Subclasses of different packages.
Can protected members be accessed by objects C++?
You can only access protected members in instances of your type (or derived from your type). You cannot access protected members of an instance of a parent or cousin type. In your case, the Derived class can only access the b member of a Derived instance, not of a different Base instance.
Who can access protected?
2. The protected Keyword. While elements declared as private can be accessed only by the class in which they’re declared, the protected keyword allows access from sub-classes and members of the same package.
Can protected members be accessed by subclass?
Protected access modifier is similar to that of private access modifiers. The data members and member functions declared public can be accessed by other classes too. The class member declared as Protected are inaccessible outside the class but they can be accessed by any subclass(derived class) of that class.
Can we override protected method as 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.
Can we override static method?
Static methods cannot be overridden because they are not dispatched on the object instance at runtime. The compiler decides which method gets called. Static methods can be overloaded (meaning that you can have the same method name for several methods as long as they have different parameter types).
Can protected members be accessed in main?
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.
How members of an object are accessed?
How members of an object are accessed? Explanation: Using dot operator after the name of object we can access its members. It is not necessary to use the pointers. We can’t use the names directly because it may be used outside the class.
Which member can never be accessed by inherited classes?
Which member can never be accessed by inherited classes? Explanation: The private member functions can never be accessed in the derived classes. The access specifiers is of maximum security that allows only the members of self class to access the private member functions.
How do you use a protected access modifier?
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. The following table shows the access to members permitted by each modifier.
How can we access protected and private members of a class?
Protected members can only be accessed by descendants of the class, and by code in the same module. Private members can only be accessed by the class they’re declared in, and by code in the same module.
Can inherited class access private members?
Private members of a base class can only be accessed by base member functions (not derived classes). So you have no rights not even a chance to do so 🙂 Well, if you have access to base class, you can declare class B as friend class. … Use protected members, if you want derived classes to be able to access them.
