Activity
1. Try to identify different objects in this faculty. Clearly describe the states and behaviors of each object.
2. Can you group them in to classes according to the common states and behaviors?
3. Try to identify the Inheritance of above mentioned classes and try to show the inheritance relationship?
4. Try to identify polymorphic behavior of defined inheritance relationship in the previous step?
ObservationAs you do, you'll notice that real-world objects vary in complexity; your desktop lamp may have only two possible states (on and off) and two possible behaviors (turn on, turn off), but your desktop radio might have additional states (on, off, current volume, current station) and behavior (turn on, turn off, increase volume, decrease volume, seek, scan, and tune). You may also notice that some objects, in turn, will also contain other objects. These real-world observations all translate into the world of object-oriented programming.

Non Academic Staff: Consider Over T Time
Student: Have a constant prices

Software objects are conceptually similar to real-world objects: they too consist of state and related behavior. An object stores its state in fields (variables in some programming languages) and exposes its behavior through methods (functions in some programming languages). Methods operate on an object's internal state and serve as the primary mechanism for object-to-object communication. Hiding internal state and requiring all interaction to be performed through an object's methods is known as data encapsulation — a fundamental principle of object-oriented programming.
