A Constructor in Java is a special method used to initialize objects. The constructor is called when an object of a class is created, and it can set initial values for object attributes. Constructors have the same name as the class and do not have a return type.
Here's how a constructor works in Java:
class Car {
// Attributes
String color;
String model;
// Constructor
Car(String c, String m) {
this.color = c;
this.model = m;
}
// Method to display car information
void displayInfo() {
System.out.println("Car Model: " + model + ", Color: " + color);
}
}
public class Main {
public static void main(String[] args) {
// Creating an object of Car
Car myCar = new Car("Red", "Toyota");
myCar.displayInfo();
}
}
