study guides for every class that actually explain what's on your next test Subclass
from class: AP Computer Science A Definition A subclass is a class that inherits properties and behaviors from another class, called the superclass. It can add new features or modify existing ones.
congrats on reading the definition of Subclass . now let's actually learn it.
