What is the primary purpose of Object-Oriented Programming (OOP)?
The primary purpose of OOP is to organize software design around 'objects' to manage complex programs more effectively.
How does a class differ from an object in OOP?
How does a class differ from an object in OOP?
A class is a blueprint or template that defines the structure and behavior of objects, while an object is a specific instance created from that class.
Give an example of a class and describe its attributes and methods.
Give an example of a class and describe its attributes and methods.
An example of a class is 'Dog', which could have attributes like breed, color, and age, and methods such as bark() and eat().
What would be an object of the class 'Car', and how could it differ from another object of the same class?

Study Notes
Overview of Object-Oriented Programming (OOP)
- OOP organizes software design around "objects" rather than actions or logic.
- This paradigm simplifies complex program management by dividing them into smaller, reusable components.
Key Concepts
-
Class
- A class serves as a blueprint or template defining the structure and behavior of objects.
- Example: A class named Car may include attributes like color and model, and methods like drive and stop.
-
Object
- An object is a specific instance derived from a class, exemplifying its attributes and methods.
- Example: myCar and yourCar can be two objects created from the Car class, possibly differing in color or model yet adhering to the same blueprint.
Detailed Example
-
Class Example: Dog
- Blueprint attributes: breed, color, age.
- Methods available: bark(), eat().
-
Object Example: myDog
- Specific instance of the Dog class.
- Attributes: breed = "Labrador", color = "Black", age = 3.
- Method call: myDog.bark() would trigger the bark action for this particular dog.
Benefits of OOP
- Enhances code organization by employing classes to model real-world entities and actions.
- Promotes reusability, making it easier to maintain and extend programs.
