a. You make it easier for anyone who has used the original class to understand the new class.

b. You save time because you need not re-create the fields and methods in the original class.

c. You reduce the chance of errors because the original class’s methods have already been used and tested.

d. You save time because subclasses are created automatically from those that come built in as part of a programming language.
