java - 当我们声明一个类而不扩展任何类时，它有父类吗？

Question

当我们声明一个类而不扩展任何类时，它是否有java中的父类？

Answer 1

是的，在几乎所有面向对象语言中，没有显式扩展的类隐式扩展基类，通常称为Object

引用:https://docs.oracle.com/javase/tutorial/java/IandI/subclasses.html

Excepting Object, which has no superclass, every class has one and only one direct superclass (single inheritance). In the absence of any other explicit superclass, every class is implicitly a subclass of Object.
