Class & Object

Class & Object

1. Class

A class is a blueprint/template used to create objects.

It defines the object's data (fields) and behavior (methods).

class Car {
    String brand;
    int speed;

    void drive() {
        System.out.println("Car is driving");
    }
}

2. Object

An object is an instance of a class that contains its own state and can perform behaviors defined by the class.

Objects are created using the new keyword.

Car car1 = new Car();

car1.brand = "BMW";
car1.speed = 120;

car1.drive();
