 * 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 methods that belong to the class itself, and not to the object of the class. They can be called without creating an instance of the class. Public methods are methods that can be accessed by any other class. They are accessible from any other class, and can be called from any other class.
 ## Part 3 - Dogs
 
 * View the image below, and from the image, construct a Java file **Dog** that mirrors the diagrammed class and the 3 dog objects.
