Question

Okay so I'm supposed to plot a couple thousand of points using the following rules

double[] cx = { 0.000, 1.000, 0.500 };
double[] cy = { 0.000, 0.000, 0.866 };
double x = 0.0, y = 0.0;
for (int i = 0; i < N; i++) {
int r = StdRandom.uniform(3);
x = (mx + cx[r]) / 2.0;
y = (my + cy[r]) / 2.0;
StdDraw.point(x, y); }}

to get Sierpinski's triangle. I can do that easily using a file for data input

java Siernpinski 10000 < sierpinski.txt where the text contains the following

but the catch is, I'm supposed to hard code this into the program AND have the starting point be user input via mouse click. I don't know how to put these two together and I keep running into problems. Here is what I have so far. Please help.

import java.applet.*;

import java.awt.*;

import java.awt.event.*;

import java.util.Scanner;

public class Sierpinski extends Applet implements MouseListener, MouseMotionListener{

int width, height;

int mx,my;

boolean isButtonPressed = false;

public void init(){

    width=getSize().width;

    height=getSize().height;

    setBackground(Color.white);

    mx=width/2;

    my=height/2;

    addMouseListener(this);

    addMouseMotionListener(this);}

   public void paint (Graphics g){

    int[] xPoints={195,65,325};

    int[] yPoints={30,255,255};

    g.drawPolygon(xPoints,yPoints,3);}

public void mouseEntered(MouseEvent e){}

public void mouseExited(MouseEvent e){}

public void mouseClicked(MouseEvent e){

    mx=e.getX();

    my=e.getY();

System.out.println(mx+","+my);

}

public void mousePressed(MouseEvent e){}

public void mouseReleased(MouseEvent e){}

public void mouseMoved(MouseEvent e){}

public void mouseDragged(MouseEvent e){}

public static void main (String args[]){

Scanner Keyboard = new Scanner(System.in);

    int N;

    System.out.println("Welcome to the Interactive Sierpinski Triangle Java App");

    System.out.println("Please enter the number of iterations that you would like to see");

    N = Keyboard.nextInt();

   double[] cx   = { 0.000, 1.000, 0.500 };

   double[] cy   = { 0.000, 0.000, 0.866 };

   double x = 0.0, y = 0.0;

        for (int i = 0; i < N; i++) {

            int r = StdRandom.uniform(3);

            x = (x + cx[r]) / 2.0;

            y = (y + cy[r]) / 2.0;

            StdDraw.point(x, y); }}

    }
