SE450: When Not to Use Inheritance [63/65]

Huh? A circle isn't a point.
By accident, inherited translate works for circles

Same tutorial makes Rectangle a subclass of Point:

public class Rectangle extends Point // DON'T 
{ 
   public Rectangle(Point corner1, Point corner2) { ... } 
   public void draw(Graphics g) { ... } 
   public void translate(int dx, int dy) { ... } 
   private Point other; 
}
