Generalpath

Question

could someone please help me with this program. I have to randomly draw triangles. I have pasted my code and it draws one triangle. I know I should use math.random but I dont know how. can someone should me how to write it in.
thanks
i
ps I love this site. it has really been a great help to me, but sometimes I am not able to sign in. Is there a problem. does it only allow so many people to be signed in at one time?

I don't know anything about general path... but I do know when dealing with random positions for drawing, most people use the int type. This little example should get you started a bit:
import java.applet.*;
import java.awt.*;
// <applet code="Example.class" width=300 height=300></applet>
public class Example extends Applet {
     Polygon[] tri; // triangles
     int[] xp, yp; // points
     int x,y,size; // position and size
     public void init() {
          tri = new Polygon[3]; // 3 triangles
          size = 20; // triangle size 20
     public void start() {
          for (int j = 0;j < tri.length;j++) { // for each triangle
               x = (int)Math.round(Math.random()*(getSize().width-size)); // random X position
               y = (int)Math.round(Math.random()*(getSize().height-size)); // random Y position
               xp = new int[] {x+size/2,x,x+size,x+size/2}; // triangle X points
               yp = new int[] {y,y+size,y+size,y}; // triangle Y points
               tri[j] = new Polygon(xp,yp,xp.length); // make triangle
     public void paint(Graphics g) {
          Color[] random = new Color[]
          { // random colors for fun
               Color.red,Color.green,Color.blue,
               Color.orange,Color.yellow,Color.cyan,
               Color.magenta
          for (int j = 0;j < tri.length;j++) {
               g.setColor(random[(int)Math.round(Math.random()*(random.length-1))]); // random color
               g.fillPolygon(tri[j]); // show triangle
}Hope it helps.
