看Oracle的官方文档
http://docs.oracle.com/javase/tutorial/java/IandI/subclasses.htmlA subclass does not inherit the private members of its parent class. However, if the superclass has public or protected methods for accessing its private fields, these can also be used by the subclass.
说的很明白,子类不能继承父类的私有成员,但可以通过父类的public或protected方法访问。
