For example, you have an interface called shape". In the bottom boxes is where we implement classes. The methods which are in the interface shape actually get implemented at the bottom, in the rectangle and circle classes. There are two types of things: classes and interfaces . Classes are related in a tree structure by inheritance. The tree goes up to the parent which, in java, is the object class. On the other hand, the interfaces are just floating around .
