Answer:
extends
Explanation:
When you create a subclass, you basically say "I'm creating a new class, but for now it will look and behave the same as that other class", then you add its own personality.
The syntax is:
class SubClass extends SuperClass
Where SubClass is your new subclass what inherits methods and variables from the SuperClass.
So, if you add nothing to the SubClass, it will be a carbon copy of the SuperClass. But you can add methods and variables exclusive to this SubClass that the SuperClass won't have.
