JAVA BEGINNERS 16 - Java Interfaces

Hi Folksss!
In this video, you learn interfaces and the keyword "implements". Often classes need the same methods and attributes. So you can use one interface and let implement it by all other classes. In this way, you write less code and you have a more organized application. Since more classes can do things differently, inside an interface you write what a class has to do but not how it does it. The "real" implementation happens in the classes themselves.
