All classes, except for Object, extend exactly one other class. If you are defining a new class and you don't explicitly specify a parent class, then its parent is Object, by default.
Why? That's just how it works. Java has a "single-rooted" object inheritance tree, like Smalltalk or the old NIH class library for C++.
