What are instance variables in Java?

What are instance variables in Java?

Instance variables are variables defined in a class but outside any method, and they are unique to each instance of the class.

Can you give me an example of instance variables?

Sure! In a class Car, you might have instance variables like color, model, and year. Each Car object can have different values for these variables.

How do instance variables differ from local variables?

Instance variables are accessible throughout the class and retain their values as long as the object exists, while local variables are only accessible within the method they are defined in.

Are instance variables initialized automatically?

Yes, instance variables are automatically initialized to default values (like null for objects, 0 for integers) if not explicitly initialized.
