Objects are memebers of a class. Mike, Jules, Lorraine, Stu, and Charlie could be workers on the night shift at our factory.
Any object is an instance of a class.
This brings in the power of the computer to assign attributes and values to objects just becuase they belong to a class. In our little example, the objects are the names, and each of them has attributes. Note that previously we could use the name of a person as an attribute. Now we are including more detail so that we need more levels of definition. Each attribute has a value.
