Constructor

What is constructor?
A constructor is a special method in Java that is used to initialize objects. It is called automatically when an object is created.

Key Features of Constructors:
Same name as the class

No return type (not even void)

Can be default (no arguments) or parameterized

Used to set initial values for object properties

Why Use Constructors?

To set default values

To create objects in a controlled way

To initialize instance variables while object creation

1.default constructor

public class Car {
Car() { // Constructor
System.out.println("Car object is created");
}

public static void main(String[] args) {
    Car myCar = new Car();  // Constructor is called here
}

}

2.Parameterized Constructor

public class Car {
String model;

Car(String carModel) {
    model = carModel;
}

public void display() {
    System.out.println("Car model: " + model);
}

public static void main(String[] args) {
    Car myCar = new Car("Honda City");
    myCar.display();
}

}
