Static Class. ambientacin de boxes de exhibicin y saln VIP en boxes, show de drift y show para Since we can have an infinite number of animal-named classes that extend our interface, we would theoretically need to add a method that simulates the behavior of an animal if its previously missing so every animal would have to implement the fly() method. We can simply let our Flying interface extend the Animal interface, and well get the same results: The code of both the Flying interface and Bird class stays the same, the only thing that changes are single lines within both of these: The Main method we used to showcase how to instantiate these objects and use them also stays the same as before. You get your encapsulation of data and functions, and you also get your abstraction. Plan de lanzamiento de productos mediante actividades tcticas de comunicacin, [] What is the best way to work around the fact that ALL Java bytes are signed?
