What is the difference between instance variables and class variables in Java?

In Java, instance variables are tied to a specific instance of a class, while class variables are shared among all instances.

Can you give me an example of each?

Sure! An instance variable is defined in a class but outside any method, and each object has its own copy. A class variable is declared with the static keyword and is shared across all instances.

How do I declare an instance variable?

You declare an instance variable by simply defining it within a class but outside any methods, like this: int instanceVar;.

And how about a class variable?

A class variable is declared with the static keyword, like this: static int classVar;. This variable is shared among all instances of the class.
