148
Q

Just as someone has to build a car from its engineering drawings before you can actually drive it, you must build an object from a class before a program can perform the tasks that the class’ methods define. The process of doing this is called _______. An object is then referred to as an _______ of its class

A

instantiation, instance

149
Q

when you drive a car, pressing its gas pedal sends a message to the car to perform a task - that is, to go faster. Similarly, you can send messages to an object. Each message is implemented as a ____ ____ that tells the method of an object to perform its task.

A

instance variables

151
Q

Classes _______ (ie, wrap) attributes and methods into objects - an object’s attributes and operations are intimately related.

encapsulation

152
Q

a new class of objects can be created quickly and conveniently by ______ - the new class absorbs the characteristics of an existing class, possibly customizing them and adding unique characteristics of its own.
