Float/Double Classes

• Rectangle2D class has no instance variables
• Template Method Pattern at work:
  

  public boolean contains(double x, double y)
  
  {
  
     double x0 = getX();
  
     double y0 = getY();
  
     return x >= x0 && y >= y0 &&
  
        x < x0 + getWidth() &&
  
        y < y0 + getHeight();
  
  }
  
  

• No need to use inner class after construction
  Rectangle2D rect
     = new Rectangle2D.Double(5, 10, 20, 30);
