Remember, objects have no prescribed sequence, typically, where one object can use other objects in whatever combination or sequence it needs to carry out the work of the program. And the benefits of object orientation include modularity, information hiding, ability to reuse code easily, and the ability to maintain the application easily. So where do the objects come from? Where does this all start? Well, technically, objects are based on classes. Objects exist at runtime, classes are used for design. Okay, where do the classes come from?
