Can you access a protected member from a Sub class outside the package of its Base class?
Protected members of a class are only accessible to its subclasses and to friends of the class or its subclasses. However, if a subclass changes the access to private, only the subclass and its friends have access but this does not affect the access rights of its ancestors or their friends.

What is mean by class access?
Class access is the ability for any given class to access the functions of another class. Private access limits access to data and code just to the class that contains the private access modifier. The so-called "default" access grants private access, as well as access to any class in the same package. Protected access grants the same as "default" access, and also allows subclasses to access the code and data. Public access allows any class in any package to access the code and data.

Why is chondrichtyes in class?

Subclasses of an abstract class that do not provide an implementation of an abtract method are also abstract?
Yes. Any class that does not provide implementation to all its methods as well as its parent class methods needs to be Abstract. The Java compiler would not successfully compile a class that does not do this.
Why do you have to retest subclasses that are instantiated from an existing class if the existing class has already been thoroughly tested?
i dont even know it !!!! that why i came to this website to find answer not for me to answer the dam question.
What are subclasses of container class?
