Static Keyword Rules
Variable / Methods marked static belong to the Class rather then to any particular Instance.
Static method/variables can be used without creating any instance of the class.
If there are instances, a static variable of a class will be shared by all instances of that class, there will be only one copy.
A static method can’t access non static variable and also it can not directly invoke non static method (But it can invoke/access method/variable via instances).
