With protected , all public members of the base class are inherited as protected in the derived class. Conversely, if the most restricting access level is specified ( private ), all the base class members are inherited as private . … Actually, most use cases of inheritance in C++ should use public inheritance.
Do protected members get inherited in Java?
Private Members in a Superclass
A subclass does not inherit the private members of its parent class. … Therefore, a public or protected nested class inherited by a subclass has indirect access to all of the private members of the superclass.
What happens to protected members in public mode of inheritance?
public inheritance makes public members of the base class public in the derived class, and the protected members of the base class remain protected in the derived class. protected inheritance makes the public and protected members of the base class protected in the derived class.
Can an inherited class access protected members?
A class can only access protected members of instances of this class or a derived class. It cannot access protected members of instances of a parent class or cousin class. In your case, the Derived class can only access the b protected member of Derived instances, not that of Base instances.
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).
Is protected inheritance is used then?
Explanation: The protected members are allowed in the same package but can also be accessed in other packages using inheritance. But the default members can never be accessible in other packages. … Explanation: The protected and public members of the parent class will become the protected members in subclass.
Which access specifier is most secure during inheritance?
Explanation: The private members are most secure in inheritance. The default members can still be in inherited in special cases, but the private members can’t be accessed in any case.
How do I access protected members?
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.
Which members of a class Cannot be inherited?
Explanation: Private members of a class can’t be inherited. These members can only be accessible from members of its own class only. It is used to secure the data. 4.
Are protected members inherited C++?
With protected , all public members of the base class are inherited as protected in the derived class. Conversely, if the most restricting access level is specified ( private ), all the base class members are inherited as private .
What is the difference between protected and private access specifiers in inheritance?
private – only available to be accessed within the class that defines them. protected – accessible in the class that defines them and in other classes which inherit from that class. Things that are private are only visible within the class itself.
Can final method be overridden?
Can We Override a Final Method? No, the Methods that are declared as final cannot be Overridden or hidden. For this very reason, a method must be declared as final only when we’re sure that it is complete.
Can we overload a final method?
private and final methods can be overloaded but they cannot be overridden. It means a class can have more than one private/final methods of same name but a child class cannot override the private/final methods of their base class. … Argument list should be same in method Overriding.
What is a protected method?
A protected method is like a private method in that it can only be invoked from within the implementation of a class or its subclasses. It differs from a private method in that it may be explicitly invoked on any instance of the class, and it is not restricted to implicit invocation on self .
