 ## Part 2 - Public VS Static
 
 * Read the W3Schools page on class methods: [W3Schools Java Class Methods](https://www.w3schools.com/java/java_class_methods.asp)
-* In your own words, write a few sentences below explaining the difference between static and public methods in relation to a class.

+* In your own words, write a few sentences below explaining the difference between static and public methods in relation to a class.          
+You must create a new object to access a public method. With a static method you do not, you can just call it at any time.          
+What you can't do however, is use static methods outside of it's own class, but you can with a public one. (Hence it's name.)
 ## 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.
