Drawing Random Triangle with Random Colours

i've been trying to get this triangle to show up with the additon of the random x, y and random r, b, g.

I do know how to get it to show up without the random numbers but with them it isn't working.

@Override
public void paintComponent(Graphics g) {
    super.paintComponent(g);

    //for (int i = 0; i < 500; i++) {
        rand = new Random();
        red = rand.nextFloat();

        rand = new Random();
        green = rand.nextFloat();

        rand = new Random();
        blue = rand.nextFloat();

        c = new Color(red, green, blue);
        g.setColor(c);


        rand = new Random();
        x1 = 1+rand.nextFloat();

        rand = new Random();
        x2 = 1+rand.nextFloat();

        rand = new Random();
        x3 = 1+rand.nextFloat();

        rand = new Random();
        y1 = 1+rand.nextInt(500);

        rand = new Random();
        y2 = 1+rand.nextInt(500);

        rand = new Random();
        y3 = 1+rand.nextInt(500);


        int[] xPoints = {(int) x1,(int) x2,(int) x3};
        int[] yPoints = {(int) y1,(int) y2,(int) y3};

        g.fillPolygon(xPoints, yPoints, nPoints);


    //}
}

public static void main(String[] args) {

    JFrame frame = new JFrame("Paint");
    frame.setSize(500,500);
    frame.setDefaultCloseOperation(frame.EXIT_ON_CLOSE);

    Draw draw = new Draw();
    frame.add(draw);
    frame.setVisible(true);
}

}
