What does a private class member mean?

The member is accessible only within its class
The member is accessible within its package
The member is accessible from any class
The member is protected and accessible in subclasses

The correct answer is: The member is accessible only within its class

A private class member means that it is only accessible within its class. This means that the member can only be used and modified by other methods or variables within its class. Other classes, even within the same package, do not have access to this private member. This is different from protected members, which can also be accessed in subclasses. Options B and C are incorrect because they imply that the member is accessible outside of its class, which is not the case for a private member. Option D is incorrect because it mentions a different access modifier, "protected", which has a different meaning than "private".
