What are constructors in Java and how do I use them?

Constructors in Java are special methods used to initialize objects. They have the same name as the class and no return type.

Can you show me an example of a constructor?

Sure! Here's a simple example:

class Car {
    String color;
    Car(String c) {
        color = c;
    }
}

In this example, the constructor Car initializes the color of the car.

What if I want to create a default constructor?

A default constructor is a constructor that takes no parameters. If you don't define any constructor, Java provides one automatically.

Can I have multiple constructors in a class?

Yes! This is called constructor overloading. You can have multiple constructors with different parameters.
