What is Protected Access?
Protected Access Modifier – Protected
Methods, fields can be declared protected, however methods and fields in a interface cannot be declared protected. Protected access gives the subclass a chance to use the helper method or variable, while preventing a nonrelated class from trying to use it.
Why is protected accessibility needed?
You need to use the protected access modifier, when you want the descendant class to see the fields / methods of the super class, BUT you do not want other classes to see these.
What is protected access specifier?
The protected access specifier hides its member variables and functions from other classes and objects. This type of variable or function can only be accessed in child class. It becomes very important while implementing inheritance.
What is private accessibility?
private: The type or member can be accessed only by code in the same class or struct . protected: The type or member can be accessed only by code in the same class , or in a class that is derived from that class .
What is 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 .
What is 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.
What are 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.
Why are methods protected?
Protecting a constructor prevents the users from creating the instance of the class, outside the package. During overriding, when a variable or method is protected, it can be overridden to other subclass using either a public or protected modifier only.
What is protected class?
The protected keyword specifies access to class members in the member-list up to the next access specifier ( public or private ) or the end of the class definition. Class members declared as protected can be used only by the following: Member functions of the class that originally declared these members.
What is protected in Java?

What is protected in C# with example?
C# Access Modifiers (Public, Private, Protected, Internal)

|internal||It is used to specifies that access is limited to the current assembly.|
What is protected class in Java?
Basically, the protected keyword is an access modifier for method and variable of a class. When a method or a variable is marked as protected, it can be accessed from: Within the enclosing class. Other classes in the same package as the enclosing class. Sub classes, regardless of packages.
What is protected internal?
The type or member can be accessed by any code in the assembly in which it is declared, OR from within a derived class in another assembly.
What is public/private and protected?
Broadly speaking, public means everyone is allowed to access, private means that only members of the same class are allowed to access, and protected means that members of subclasses are also allowed.
What is protected in Python?
Protected variables are those data members of a class that can be accessed within the class and the classes derived from that class. In Python, there is no existence of “Public” instance variables.
