How do I access instance variables in Java?

In Java, you can access instance variables using the dot operator on an object of the class. For example, if you have a class Car with an instance variable color, you can access it like this: myCar.color.

Can you give me an example of a class with instance variables?

Sure! Here's a simple example:

class Car {
    String color;
    int year;

    Car(String color, int year) {
        this.color = color;
        this.year = year;
    }
}

You can create an object of Car and access its instance variables.

What if I want to change the value of an instance variable?

You can change the value of an instance variable by assigning a new value to it. For example:

myCar.color = "Red";

This will change the color of myCar to red.

Are instance variables private by default?

No, instance variables are not private by default. They have package-private access if no access modifier is specified. You can make them private by using the private keyword.
