One of the new interface features in Java 8 is the ability to incorporate static methods. Basically all the same rules of an ordinary static method in a class apply to a static method in an interface. I created an extensive two part tutorial on static methods, Static Methods Part 1 and Static Methods Part 2. If you are not familiar with a static method, please watch those tutorials because I won't be spending much time explaining how a static method works, but rather I will be demonstrating their use in an interface.
