    • A case of dynamic dispatching
      • Dynamic dispatching is what makes polymorphic behavior happen. When you call toString() on an object, the right implementation is called because Java dispatches to the appropriate method based on the type of the instance. But Java doesn’t go the whole length when it comes to dynamic dispatch: while it pays attention to the actual type of the instance, it only concerns itself with the type of the reference to any parameters, not their actual types
