Answer 1

The correct keyword to use to indicate that a subclass extends a superclass is 'extends'.

Step-by-step explanation:

The correct keyword to use to specify that a subclass extends a superclass is extends.

When defining a class in Java, the keyword extends is used to indicate that the class is a subclass of another class, which is called the superclass.

For example, the correct syntax for defining a subclass called Subclass that extends a superclass would be: public class Subclass extends Superclass {}So, as you drop down in the hierarchy, the classes become more and more specialized: Definition: A subclass is a class that derives from another class. A subclass inherits state and behavior from all of its ancestors. The term superclass refers to a class's direct ancestor as well as all of its ascendant classes.
