Java Fractal

[HeavenAgain]

well, i dont see any java graphics being posted on this forum, so i'll share one of "mine"
its not that pretty and all, but i hope it will get people started thinking about recursions, and graphics

code:

import javax.swing.JFrame;     //imports for the frame import java.awt.Color;         //imports the colour import java.awt.Graphics;    //imports the graphics import java.util.Random;  // imports the random class for random colour public class SierpinskiSquare {   public static void main (String[]args)   {     new SFrame();  // call to the frame, program   } } class SFrame extends JFrame {   Graphics g;     // graphics   Color c =Color.WHITE; // set colour to white to creat the blanks   Random r = new Random();   public SFrame()   {     setTitle("Sierpinski Square"); // name of the window/frame     setVisible(true); // true to show the window     setSize(500,500); // creats the frame, starting window visible true     //  setResizable(false); //cannot resize the frame/window     --  useless, since fratal base is on window size     setLocationRelativeTo(null); //center the frame/window     setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //exit window, omit this line to avoid annoying pop up, useless     //   setBackground(Color.WHITE); //set background to white   }   public void paint(Graphics g)   {     this.g = g;     repaint(); // incase if the window size is change, then "refresh" page, useless since window size never change     drawSierpinskiSquare( 0, 0, getWidth(), getHeight());     // start recursion   }   private void drawSierpinskiSquare ( int x, int y ,int w, int h)   {     if (w>2 && h>2) //control when to stop     {              int nw=w/3, nh=h/3;    // the new square's width and height       g.setColor(c);          //random colour (default is white)       g.fillRect ( x+nw,y+nh,nw,nh);  //draws and fill the square, bigger one       for (int k=0;k<9;k++)         // inside the big square, divide it into 9 smaller one equally         if (k!=4)                  // if is not the middle square       {                          c=new Color( r.nextInt(256), r.nextInt(256), r.nextInt(256));      //makes the new colour         int i=k/3, j=k%3;                                     // dividing the 8 equal squares into another 9 smaller ones         drawSierpinskiSquare ( x+i*nw, y+j*nh, nw, nh );                 // draws out the recursion       }     }   } }

feel free to put any comments on it
oh, and the logic behind it is here

That's pretty cool. It looks like a processor.

code:

import javax.swing.JFrame import java.awt.{Color, Graphics} import java.util.Random import Color.WHITE import JFrame.EXIT_ON_CLOSE object SierpinskiSquare extends Application {     new SFrame } class SFrame extends JFrame("Sierpinski Square") {     var g: Graphics = null     var c = WHITE     val r = new Random     this setVisible true     this setSize (500, 500)     this setLocationRelativeTo null     this setDefaultCloseOperation EXIT_ON_CLOSE     override def paint(g: Graphics) {         this g = g         this repaint ()         this drawSierpinskiSquare (0, 0, getWidth, getHeight)     }     def drawSierpinskiSquare(x: Int, y: Int, w: Int, h: Int) {         def rand = r nextInt 256         if (w > 2 && h > 2) {             val nw = w / 3             val nh = h / 3             g setColor c             g fillRect (x + nw, y + nh, nw, nh)             for (val k <- 0 to 9 if k != 4) {                 c = new Color(rand, rand, rand)                                 val i = k / 3                 val j = k % 3                         this drawSierpinskiSquare (x + i * nw, y + j * nh, nw, nh)             }         }     } }

Food for thought.

ummm wtd, what java language is that? looks neat

That, unless I'm very much mistaken, is Scala
