Muito bem explicado e com muita riqueza de detalhes . Aqui no youtube eu nunca tinha assistido alguém explicar tão bem um assunto. ( vielen Dank Marcus.)

In this episode I’m going to talk about interfaces in Java. Interfaces are probably the most powerful feature of object-oriented languages.
Before I continue, first of all some organizational stuff, so this video is divided into three parts. Part 1 I will first of all talk about the definition, what does actually the word interface mean and tell you a bit about the history, like how were interfaces introduced into Java. I’ll make this part as short as I can, not to put you to sleep. And then second, we’ll jump into my IDE, we’ll do a short coding session and I show you how to practically use interfaces in Java. Last but not least, I’ll do a short discussion about the pros and cons of interfaces from a clean coder’s perspective...

What if you wanted the same BMW to print the owner from the property interface, now you have created a car?
