子类是否继承超类的关联类

Question

I just want to clear a concept of inheritance. Do sub classes inherit the associated classes of super class. To make my question clear let suppose an example Assume there is a super class Person, having association relationship with BloodGroup class and Address class, and Women and Men as its sub classes, now tell me whether the Sub Classes will inherit these two associated classes from parent class or not?

Answer 1

是的，如果它们是public或protected 。

Answer 2

子类继承其父类的除私有字段之外的所有字段。

Answer 3

A subclass will only inherit the structure (methods and properties) of it's superclass and it's superclass's superclasse's.

If by associated classes you mean import. The subclass does not inherit the super's imports. Imports are file specific and used for compilation of individual .java files.

ie

Object
 -Person extends Object
    -Male extends Person

Male can use and override the methods and properties of both Person and Object as long as the access modifiers(public/protected/private/package) allow it. Male does not care what objects are used in the methods or what code is run in them, it only uses them based on it's signature(returnType methodName(Parameters)).
