1.1 Object Oriented Programming

1.	Everywhere you look in the real world you see objects such as people, animals, plants, cars, buildings and

so on.

2.	These objects have some things in common.

a.

They all have attributes (e.g. size, shape, color and weight).

b.

They all have behavior (e.g. people walk and eat, cars accelerate, brake and turn).

3.	We can learn objects by studying their attributes and observing their behavior.

4.	Different objects can have similar attributes and can have similar behavior.

5.	Object orientation views the real world as objects with some things in common. They all have attributes

and behavior.

6.	There is a close match between objects in the programming sense and objects in the real world.

7.	When approaching a programming problem in an object-oriented language, we try to divide the problem

into objects.

8.	Thinking in terms of object rather than functions has a helpful effect on how easily we can design

programs.
