The unique existence of every object, independent of its characteristics You might see object described elsewhere using different terminology, but don't worry too much about that. Grasping the concepts is the important thing. Let's further explore the notion of type. We're almost always dealing with many different objects, and the natural inclination is to classify or label them in some way. A type is the way to classify objects, and it's also the blueprint that defines the behavior and properties for objects of a certain type.
Every object has a type associated with it, and possibly more than one type.
Let's examine the alarm clock type. We'll take a crack at determining its behavior and properties. We'll talk more about this later when we delve into the best way to actually program a type. We buy an alarm clock and bring it home. We set the current time and the alarm time.
