Thread: 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);
    }
}
 {
 }

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.
