This misconception results from not understanding the differences between classes and objects. As stated in M&C 2, a class is like a blueprint for a house, a cookie cutter for a cookie, etc. The blueprint of a house describes the overall design, appearance, layout, and structure of a house. Actual houses are “instances” of this blueprint.
Therefore, a class is not a collection of instances, but rather a template of its instances. We need to initialize new instances of the class when we want to use objects. For example, the class Appliance is the template to build the object stove and the object computer.
