Until now, we have not been doing much with objects.
This chapter discusses objects and classes.
Forget programming for a while. Think about the Real World and the things that are in it. What things are objects? What things are not objects? This is actually a difficult problem which has occupied philosophers for thousands of years. Don't be too worried if it is not immediately clear to you.
Look around you. List four objects and list four non-objects.
