Is protected accessible within package?

Is protected package private?
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 (as with package-private) and, in addition, by a subclass of its class in another package.
Can a protected method be accessed outside the package?
While protected members can be accessed anywhere in the same package and outside package only in its child class and using the child class’s reference variable only, not on the reference variable of the parent class.
Is protected better than private?

What does package Private mean?
package-private (often just called package) means that other members of the same package have access to the item. package-private is the default access modifier and does not have a keyword, because package is used to specify the package for a class or interface.
What is meant by protected visibility of a method?
The default visibility allows access by other classes in the package. Figure 6-7. Private, default, protected, and public visibility. The protected modifier allows special access permissions for subclasses. Contrary to how it might sound, protected is slightly less restrictive than the default level of accessibility.
How do I access protected methods?
The method displayed in class A is protected and class B is inherited from class A and this protected method is then accessed by creating an object of class B.
- Within the same class.
- Subclasses of the same packages.
- Different classes of the same packages.
- Subclasses of different packages.
How do you access protected variables outside a class?

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 .
What is the difference between public protected package private and private in Java?

What is a protected variable?
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. However, we use underscore ‘_’ symbol to determine the access control of a data member in a class.
How protected visibility is different from public visibility?
Class members declared public can be accessed everywhere. Members declared protected can be accessed only within the class itself and by inherited and parent classes.
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.
