, -Sam was asked to create a DeliveryDriver class. Sam thought about the
problem, and reduced it to its most essential aspects... things like takeOrder,
DeliveryArea, etc. She ignored things that were not important in the context,
like the driver's height or eye colour. She just applied an important object-
oriented design principle. Which of these concepts best describes what she
just did? ([file: Image1.PNG])
a. abstraction
b. generalization
c. decomposition
d. encapsulation - -a
-Sam identified the important attributes and behaviours of a delivery driver

and "DeliveryArea." She exposed some of these to other classes. She just
demonstrated an important part of object-oriented design. Which of these
concepts best describes what you did?
a. generalization
b. abstraction
c. encapsulation
d. decomposition - -c

design principle?
a. decomposition
b. abstraction
c. encapsulation
d. generalization - -a
-Sam realized that her DeliveryDriver class had some behaviour and
