Difference between static data members and non static data members:

Static data members	Non Static data members
static data members are declared with static modifier.	Non static data members are declared without  static modifier
Static data members are created in class memory	Non Static data members are created in object memory
We can access static data members by using class name or by using reference pointing object or pointing to null.	We can access non static members only using object or object pointing to reference.
Static data is common for all objects	Non static data is specific for each and every object
Static variables are called class variables.	Non static variables are called as instance variables or object variables.
Static data can be access in both static and non static methods.	Non static data can be access only in non static methods.
