What are class variables in Java?

Can you explain what class variables are in Java?

Sure! Class variables in Java are static variables that belong to the class rather than to any specific instance.

How do you declare a class variable?

You declare a class variable using the 'static' keyword. For example: 'static int count;'

What is the difference between class variables and instance variables?

Class variables are shared among all instances, while instance variables are unique to each object.

Can you give me an example of using class variables?

Certainly! If you have a class 'Car' with a static variable 'numberOfCars', it keeps track of how many cars have been created.
