Q 9 – Which of the following is true about protected access modifiers? A – Variables, methods, and constructors that are declared protected can be accessed by any class.
What is the protected access modifier used for?
Protected Access Modifiers – Protected Protected access gives subclasses the opportunity to use a helper method or variable and prevents unrelated classes from attempting to use it.
Which of the following can be used as access modifier of a method?
Access modifiers are modifiers that restrict access to classes, constructors, data members, and methods of another class. Therefore, there are four access modifiers: – default, private, protected, and public. public – With this modifier, members, methods, and classes are declared as public and can be accessed from anywhere.
What is protected access specifier?
Remarks. The protected keyword specifies access to a class member in the member list until the next access specification (public or private) or the end of the class definition. Class members declared as protected may only be used in member functions of the class that originally declared these members.
Which of the following statement describes about protected access specifier for fields methods?
Which of the following best describes a protected specification? Explanation: Protected members are safest when inheritance is not used. However, this facility is provided to keep these members private, thereby allowing them to be inherited by other classes.
Who can access protected methods in Java?
2. Protected keywords. Elements declared as private can only be accessed in the class in which they are declared, while protected keywords allow access from subclasses and members of the same package.
Which of the following can be used as access modifier of a method Mcq?
Explanation: Variables or methods marked as private can only be accessed within the class. External classes cannot access them. Private is therefore the most restrictive access modifier in Java.
Which of the following statement is about access modifiers in Java?

Where can a protected member be accessed?
Protected members of a class are similar to private members because they cannot be accessed from outside the class. Private members cannot, however, but can be accessed in derived or child classes.
How are protected members of a base class Mcq?
Explanation: Protected members are inheritable and can be accessed in derived classes, which is the difference between the protected and private access specifications of inheritance.
Which of the following best explains the access modifier private?
Members have access to the class itself and its derived classes. Which of the following best describes a private access specification? Members have access only to the class itself.
Which of these access specifiers must be used for main () method private/public protected none of the mentioned?
1. Which of these access specifications must be used for the main() method? Explanation: The main() method must be exposed so that it can be called by the non-program Java Run Time System. If no access specification is used, then by default the member is exposed in its own package and cannot be accessed by the Java Run Time System.
Which among the following can use protected access specifier?
1 Answer. Explanation: members that are safe and may be used in other packages or subclasses can use protected access. This allows the member to be safe from accidental changes.
Which of the following access modifier can be accessed with in a class private protected public?
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 (similar to Package Private), and further specifies that it can be accessed by subclasses of classes in another package.
Can protected methods be accessed by classes in different package?
Protected allows access by subclasses or other classes in the same package. Thus, derived class instances can access the protected way of the base.
Can protected methods be overridden?
Yes, SuperClass protected methods can be overridden by subclasses. If a SuperClass method is protected, the overridden method of the subclass can be protected or not exposed (not default or private).
Which of the following is not access specifier modifier in Java?

What is the difference between protected and private access specifier?
In C ++, there are three access specifications Public – members can be accessed from outside the class. Private – members are not accessible (or visible) from outside the class. Protected – members cannot be accessed from outside the class, but can be accessed in inherited classes.
What is access control specifier explain public access control specifier with example?
Public Access Specification. The C ++ access specification is used to determine or set the boundaries of availability of class members (data members and member functions) beyond their class. For example, class members are privately protected sections, publicly accessible.
Which statement is true about accessibility of members?
Which statement applies to member accessibility? The package/default accessibility of a member can be declared using the keyword default.
What are protected members explain in detail?
Public vs. Protected Differences
| Public | Protected. |
|---|---|
| Public data members and member features can be accessed by other classes. | Class members declared as protected are not accessible outside the class, but can be accessed by any subclass (derived class) of that class. |
What does derived class does not inherit from the base class in C++ Mcq?
Explanation: In C ++, the constructor and destruction of a class cannot be inherited by a derived class. However, when an object of a derived class is created, the constructor of the base class is automatically called. You can read the order of execution of the constructor and destructor calls in C ++ inheritance.
Which statement is true with regard to private and protected members of a class?
D. Protected members of a class can be inherited by a subclass and become private members of the subclass. Explanation: Private members of a class cannot be inherited by subclasses.
What is the difference between public and protected access modifiers?
With protected access modifiers, data members can be accessed by class, package, subclass (same package), and subclass (different package). The difference between public and protected is that public can be accessed by external classes, but protected cannot be accessed by external classes.
What is the difference between public/private and protected access modifier?
Protected members are not accessible from non-child classes of the external package. Package members cannot be accessed from non-child classes of the outer package. Public modifiers are the most accessible of all modifiers. Private modifiers are the most restricted of all modifiers.
How can a protected modifier be accessed?

What is protected access specifier?
Remarks. The protected keyword specifies access to a class member in the member list until the next access specification (public or private) or the end of the class definition. Class members declared as protected may only be used in member functions of the class that originally declared these members.
Why we use protected access specifiers?
The protected access specification allows the class to which the member belongs, its friends, and derived classes to access the member. However, protected members cannot be accessed from outside the class.
Which of the following can be used as access modifiers of a method?
Access modifiers are modifiers that restrict access to classes, constructors, data members, and methods of another class. Therefore, there are four access modifiers: – default, private, protected, and public. public – With this modifier, members, methods, and classes are declared as public and can be accessed from anywhere.
