Need to paint objects from one applet into another

Question

Maybe this question is more at home here; I have an applet test program which uses the timer class to make a car drive across the screen. The test works fine with the rectangle I used, but now I need to use the car created in this class:
   import java.applet.Applet;
   import java.awt.Graphics;
   import java.awt.Graphics2D;
   import java.awt.Rectangle;
   import java.awt.geom.Ellipse2D; 
   import java.awt.geom.Line2D;
   import java.awt.geom.Point2D;
     public class Car extends Applet
          public void paint(Graphics g)
               Graphics2D g2 =(Graphics2D)g;
               Rectangle body =new Rectangle(100, 110, 60, 10);
               Ellipse2D.Double frontTire =new Ellipse2D.Double(110, 120, 10, 10);
               Ellipse2D.Double rearTire =new Ellipse2D.Double(140, 120, 10, 10);
               Point2D.Double r1 =new Point2D.Double(110, 110);
               //the bottom of the front windshield
               Point2D.Double r2 =new Point2D.Double(120, 100);
               //the front of the roof
               Point2D.Double r3 =new Point2D.Double(140, 100);
               //the rear of the roof
               Point2D.Double r4 =new Point2D.Double(150, 110);
               //the bottom of the rear windshield
               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);
     }The only thing I could think of was making an object of type Car in the test program and then doing something like this:
Car c =new Car();
g2.draw(c.paint(g));
But it says in the test program void type not allowed here. Any tips as to what I'm doing wrong? My guess is that its a problem in the Car class and not the test program, but I didn't think I was supposed to alter Car. (Plus I tried already and couldn't get it to work.)

Answer 1

what? I don't see what you are trying to do..
You are trying to make an instance of a class which has no constructor?
You are trying to move a Panel (an Applet is a subclass of Panel) in another Panel (in Test class?)
Keep in mind that the Panel automatically has flow layout. In flow layout the components are sized to minimum size, and if the component is another Panel, the minimum size is 0 if there are no components in it.
Do you need both applets open at once?
Why not just copy this paint code into your test class?
Also note that you CAN copy the Graphics from one component onto another, but the Graphics object cannot be null, or you will get a NullPointerException... which is what will happen if you try to copy it in the init() of your test class.
Why not just make your car a Component (or a Panel even) and give it a constructor? (And make sure to set minimum size to something other than zero?)
I think you have more than one problem..
