 * In your own words, write a few sentences below explaining the difference between static and public methods in relation to a class.
 
+Static methods are associated with the class itself rather than with instances of the class. They can be called directly using the class name, without needing to create an object of the class. Static methods are commonly used for utility functions or operations that do not require access to instance variables.
+
+On the other hand, public methods are instance methods that are associated with individual objects or instances of the class. They can access instance variables and are typically called using an object of the class. Public methods define the behavior of objects and can modify the state of an object's instance variables.
