    Default Make a polygon appear in random places using Japplet and Canvas

    I can make the circles appear in random places, but need a little direction to make the polygon appear in random places.

    import java.awt.*;
     
    public class Circle
    {
        private int number;
        private int diameter;
        private Color colour;
     
        public Circle(int num)
        {
            number = num;
            diameter = randomInt(20, 50);
            colour = new Color(randomInt(0, 255),randomInt(0, 255),randomInt(0, 255));
        }
     
        public int getDiameter()
        {
            return diameter;
        }
     
        private int randomInt(int min, int max)
        {
            return (int)(Math.random() * (max - min + 1) + min);
        }
     
        public void display(Graphics g, int x, int y)
        {
            int radius = diameter / 2;
     
            //THE POLYGON IS SET IN ONE PLACE
            int[] polyx = {6, 59, 84, 126, 151, 194, 194, 6};
            int[] polyy = {47, 47, 27, 27, 47, 47, 77, 77};
            g.setColor(colour);
            g.fillPolygon(polyx, polyy, 8);
     
            //THE CIRCLES ARE DRAWN IN RANDOM PLACES
            g.setColor(colour);
            g.fillOval(x, y, diameter, diameter);
            g.setColor(Color.BLACK);
            g.drawOval(x, y, diameter, diameter);
            g.drawString("" + number,  x + radius, y + radius);
        }
    }
     {
     }

    Do you want the shape to stay the same and only the location to move?
    Chose a new x,y location and add the new values to all the x and y values that define the polygon.
    If you don't understand my answer, don't ignore it, ask a question.

    the polygon is a car shape, and I've got to make 10 cars appear randomly in the applet. So everytime the Applet is run they all appear in different places.
