What is a constructor in Java?

Can you explain what a constructor is in Java?

Sure! A constructor in Java is a special method used to initialize objects. It is called when an object of a class is created.

What are the different types of constructors in Java?

There are two main types of constructors: default constructors, which take no parameters, and parameterized constructors, which take arguments to set initial values.

Can you give me an example of a parameterized constructor?

Of course! Here's a simple example:

class Car {
    String model;
    int year;

    // Parameterized constructor
    Car(String model, int year) {
        this.model = model;
        this.year = year;
    }
}

This constructor initializes the model and year of the car.

What happens if I don't define a constructor in my class?

If you don't define any constructor, Java provides a default constructor that initializes object fields to their default values.
