How do I use parameters in constructors in Java?

In Java, you can use parameters in constructors to initialize object attributes. For example, if you have a class Car, you can create a constructor that takes parameters like make and model.

Can you show me a code example?

Sure! Here's a simple example:

public class Car {
    private String make;
    private String model;

    public Car(String make, String model) {
        this.make = make;
        this.model = model;
    }
}

In this example, the constructor takes make and model as parameters and assigns them to the object's attributes.

What if I want to set default values?

You can overload the constructor. For instance, you can create another constructor that doesn't take parameters and sets default values:

public Car() {
    this.make = "Default Make";
    this.model = "Default Model";
}
