Answer 1

Take car class  class instead of shape in file 1
public class Car
{
   public Car(double x, double y)
   {
      xLeft = x;
      yTop = y;
   }
   public void draw(Graphics2D g2)
   {
      Rectangle2D.Double body 
         = new Rectangle2D.Double(xLeft, yTop + 10, 60, 10);      
      Ellipse2D.Double frontTire 
         = new Ellipse2D.Double(xLeft + 10, yTop + 20, 10, 10);
      Ellipse2D.Double rearTire
         = new Ellipse2D.Double(xLeft + 40, yTop + 20, 10, 10);


      Point2D.Double r1 = new Point2D.Double(xLeft + 10, yTop + 10);
   
      Point2D.Double r2 = new Point2D.Double(xLeft + 20, yTop);
     
      Point2D.Double r3 = new Point2D.Double(xLeft + 40, yTop);
      Point2D.Double r4  = new Point2D.Double(xLeft + 50, yTop + 10);

      Line2D.Double frontWindshield 
         = new Line2D.Double(r1, r2);
      Line2D.Double roofTop 
         = new Line2D.Double(r2, r3);
      Line2D.Double rearWindshield
         = new Line2D.Double(r3, r4);
   
      g2.draw(body);
      g2.draw(frontTire);
      g2.draw(rearTire);
      g2.draw(frontWindshield);      
      g2.draw(roofTop);      
      g2.draw(rearWindshield);      
   }

}

Do modification in file 1 in switch case as given below

Car shape;

switch (brand){ case "A": shape= new car.FLOAT(pos,pos,pos,pos)....}
