Problem

1. Every BMW is a vehicle. Should a class BMW inherit from the class Vehicle? BMW is a vehicle manufacturer. Does that mean that the class BMW should inherit from the class Vehicle Manufacturer?

2. Some books on object-oriented programming recommend using inheritance so that the class Circle extends the class java.awt.Point.

Why is it nevertheless not a good idea to have Circle inherit from Point? Conversely, would inheriting Point from Circle fulfill the is-a rule? Would it be a good idea?
