Answer
# 1
In object-oriented programming, a class is a construct that
is used as a blueprint (or template) to create objects of
that class. This blueprint describes the state and behavior
that the objects of the class all share. An object of a
given class is called an instance of the class. The class
that contains (and was used to create) that instance can be
considered as the type of that object, e.g. an object
instance of the "Fruit" class would be of the type "Fruit".
