If one class inherits another class, can it use inherited class' private methods, fields, constructor?

This question in regards to a quiz question: If all parts of a class (fields, methods, constructor, etc) are declared private is there any way for other classes to use this class?

So, the correct answer is No. However, if another class inherits this class, then it could use all the private fields, methods, constructor, etc., couldn't it? If so, then the correct answer is Yes.

No, private fields cannot be used by inheritance.

That's what "protected" is for. It allows use through inheritance, but it's not public.
