 * In your own words, write a few sentences below explaining the difference between static and public methods in relation to a class.
+- In java the static method is particularly useful because it's easy to access later in the program, whereas the public method is more difficult to access without something else in the program . The difference between static and public is that the static method can be used without already having an object in the code and the public method is only useful for existing objects.
