Difference between class and instance variables. Now, it should be clear what the difference between instance and class variables is. Class variables only have one copy that is shared by all the different objects of a class, whereas every object has itâs own personal copy of an instance variable. So, instance variables across different objects can have different values whereas class variables across different objects can have only one value.
Part of the Programming glossary: In object-oriented programming, a class is a template definition of the method s and variable s in a particular kind of object. Thus, an object is a specific instance of a class; it contains real values instead of variables. The class is one of the defining ideas of object-oriented programming. Among the important ideas about classes are: 1  A class can have subclasses that can inherit all or some of the characteristics of the class. 2  In relation to each subclass, the class becomes the superclass.
