What it is? And How it/each of it works? ATTRIBUTE and CLASS of Determining "Specific" Functionality as it/each of it should be!

Attribute and Method of a Class in Object-Oriented Programming (OOP)

In Object-Oriented Programming (OOP), a class is a blueprint used to create objects. Inside a class, there are two important components: attributes and methods.

---

1. Attribute (Property / Field)

An attribute is a variable inside a class that stores the data or state of an object.

• It represents what an object has.
• Each object created from the class will have its own values for these attributes.

Example

Class: Car

Attributes:

• brand
• color
• speed

Example in pseudocode:

class Car:

    brand = ""

    color = ""

    speed = 0

Explanation:

• brand → stores the car brand (Toyota, Honda, etc.)
• color → stores the color of the car
• speed → stores the current speed

If an object is created:

myCar = Car()

myCar.brand = "Toyota"

myCar.color = "Red"

myCar.speed = 120

Here, brand, color, and speed are attributes.

2. Method (Function / Behavior)

A method is a function inside a class that defines the behavior or actions of the object.

• It represents what an object can do.

Example

class Car:

    def start(self):

        print("Car is starting")

    def accelerate(self):

        print("Car is accelerating")

    def brake(self):

        print("Car is braking")

Explanation:

• start() → action to start the car
• accelerate() → action to increase speed
• brake() → action to stop the car

Using the object:

myCar = Car()

myCar.start()

myCar.accelerate()

Here, start() and accelerate() are methods.

3. Simple Analogy

Example: Smartphone

Attributes (data):

• brand
• battery level
• storage
• screen size

Methods (actions):

• turnOn()
• turnOff()
• call()
• sendMessage()

Component	Meaning	Example
Attribute	Data owned by object	color, speed
Method	Action performed by object	start(), stop()

---

4. Short Definition

• Attribute → variable that stores object data.
• Method → function that defines object behavior.

---

Summary

In Object-Oriented Programming, a class contains:

• Attributes → describe the state or data of objects
• Methods → define the behavior or actions of objects

Objects created from the class use these attributes and methods.
