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 protected access specifier with example?
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 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.
Is private access specifier in Java?
Private: The private access modifier is specified using the keyword private. The methods or data members declared as private are accessible only within the class in which they are declared. Any other class of the same package will not be able to access these members.
Why we use protected access specifiers?
The protected access specifier allows the class the member belongs to, friends, and derived classes to access the member. However, protected members are not accessible from outside the class.
What is protected in OOP?
Protected means that a class and its subclasses have access to the variable, but not any other classes, they need to use a getter/setter to do anything with the variable. A private means that only that class has direct access to the variable, everything else needs a method/function to access or change that data.
How a protected access specifier differs from private access specifier?
Private members are accessible within the same class in which they are declared. Protected members are accessible within the same class and within the derived/sub/child class. Private members can also be accessed through the friend function. Protected members cannot be accessed through the friend function.
What is difference between private and protected access specifier?
Private = only members of the same class can access the function. Protected = Same as private but derived classes can also access.
What is the difference between default and protected in Java?
What are the differences between protected and default access specifiers in Java? The Protected access specifier is visible within the same package and also visible in the subclass whereas the Default is a package level access specifier and it can be visible in the same package.
When should I use protected in Java?
Use the protected modifier when you need to only allow access to the code within the package or when its subclassed.
What is protected in Java with example?

Why we use protected keyword in Java?
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.
What is an anonymous class in Java?
Anonymous classes enable you to make your code more concise. They enable you to declare and instantiate a class at the same time. They are like local classes except that they do not have a name. Use them if you need to use a local class only once.
What is static in Java?
In the Java programming language, the keyword static means that the particular member belongs to a type itself, rather than to an instance of that type. This means we’ll create only one instance of that static member that is shared across all instances of the class.
What are access specifiers and access modifiers in Java?
Access Specifier is used to provide your code in Java whether other classes can access your code or not. Access Modifier provides both Access Specifier and Access Modifiers for creating access to your Java code for other classes. Here modifier is also used to do the same task but there are limitations.
Why we use protected private and public access specifiers?
public – members are accessible from outside the class. private – members cannot be accessed (or viewed) from outside the class. protected – members cannot be accessed from outside the class, however, they can be accessed in inherited classes. You will learn more about Inheritance later.
Which access specifier is implicitly used in a class?
The private access specifer is implicitly used in a class.
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.
