Answer 2

Answer:

In Java, we use the extends keyword to inherit from a class. Here, we have inherited the Dog class from the Animal class. The Animal is the superclass (parent class or base class), and the Dog is a subclass (child class or derived class). The subclass inherits the fields and methods of the superclass.
