Which keyword is used by a Java class to inherit from another class?

Concept

In Java, class-to-class inheritance creates a subclass–superclass relationship.

A subclass declaration names its direct superclass with the keyword extends.

Application

1. For example, class Child extends Parent {} declares Child as a subclass of Parent.

2. Child can inherit the accessible fields and methods of Parent.

Contrast and cross-check

• implements connects a class to one or more interfaces; it does not name a superclass.

• inherits is an English verb used to describe inheritance, not Java declaration syntax.

• The set choices “More than one of the above” and “None of the above” do not apply because one listed keyword has the specified class-to-class role.

Therefore, the required keyword is extends.
