A class variable is a variable that is declared as static. This variable can be accessed even before the object of the class is created. i.e it would be available when the class is loaded. Where as instance variable is a variable that is declared at class level without the keyword static.

A class variable which is declared as static is common to all the instances of the Class, i.e if you make any change in the class variable it applies to all the objects created for the class. In case of Instance variable- each object created for the class has its own instance variable copy.

Static variable, the field is allocated when the class is created. It belongs to the class and not any object of the class. It is class variable.

Instance variable, the field is allocated when the class is instantiated to the class is called instance variable or non-static variable

Static variable has only one copy for all the methods in class while instance variable has many copy.

Class can access only static variable while object can access both class and instance variable.

Class variable :: It is a variable which we can access this variable by using class name and another advantage is when the class loads in ClassLoader(i.e JVM) at that time itself the variable is initiated. Best examples of class variables are static variables.

Instance variable :: It is a object variable i.e when we create that object for that particular class then only we can access this varable i.e objectName.instanceVariableName.
