Instance variables(or object variable) are fields that belongs to a particular instance of an object.Static variables (or class variable) are common to all the instance of the same class. Here's an example:usage:n the same class, we have an object variable, flavor. This is dependent on the instance of the class, and is set in the constructor. So now you can access this specific muffin's flavor by calling myMuffin.flavor. Notice how we need to instantiate a Muffin object before we can access its flavor.
