The do all inherit form java.lang.Object because every class in Java does.
A Window is an abstract class that defines a standard set of behaviors that its descendants will have. The View class inherits from Window and provides a basic implementation of how to create a rectangular region of the screen that can draw itself and be interacted with by the user. The Dialog class does *not* inherit from View or Window. It provides a basic implementation for presenting a control the user will interact with. It is a bit surprising to me that Dialog does not inherit from View, but I can see how Dialogs have enough specific features where it would have its own base class.
