How do I use constructors in Java?

In Java, a constructor is a special method used to initialize objects. It has the same name as the class and does not have a return type.

Can you show me an example of a constructor?

Sure! Here's a simple example:

class Car {
    String color;
    String model;

    // Constructor
    Car(String c, String m) {
        color = c;
        model = m;
    }
}

This constructor initializes the color and model of the Car object.

What if I want to create a default constructor?

A default constructor is a constructor that does not take any parameters. You can create one like this:

class Car {
    String color;
    String model;

    // Default Constructor
    Car() {
        color = "Unknown";
        model = "Unknown";
    }
}

Can constructors be overloaded?

Yes, constructors can be overloaded in Java. You can have multiple constructors with different parameter lists in the same class.
