Static method and Non Static method

`A static method is one that belongs to a class instead of an instance of a class
A static method is a part of the class itself rather than an instance of a class.
The method is available to each instance of the class.
Static methods can be accessed directly in non-static and static methods
Static methods are accessed through the class name, rather than an object of the class
