Access modifiers can be given to the instance variable. An instance variable is not a class variable, [4] although there are similarities. Both are a type of class attribute (or class property, field, or data member). While an instance variable's value may differ between instances of a class, a class variable can only have one value at any

A class variable is not an instance variable. It is a special type of class attribute (or class property, field , or data member). The same dichotomy between instance and class members applies to methods ("member functions") as well; a class may have both instance methods and class methods .

For example, if a date is represented by separate private year, month and day variables, then incoming dates can be split by the setDate mutator while for consistency the same private instance variables are accessed by setYear and setMonth.
