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 no return type.

Can you give me an example of a constructor?

Sure! Here's a simple example:

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

This constructor initializes the color of the car when a new object is created.

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. Here's how you can define one:

class Car {
    String color;
    Car() {
        color = "red";
    }
}

Can constructors be overloaded?

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