Dec 10th, 2007
Hi there.This is my first post here.I need help urgently.
I getting desperate because I got a deadline for a project in 3 weeks time.I'm trying to do a 2 X 2 matrix multiplication applet that simulate systolic architecture.Should be something like the Wallace Tree Simulation. It can be seen here:

http://media.pearsoncmg.com/aw/aw_ca...sys_1/wallace/

I got little knowledge of Java but I have to finish this in 3 weeks time.
Anyone expert in Java that could help me here?
Here it is the code that I did so far:
java Syntax (Toggle Plain Text) 
  1. import java.applet.*;
  2. import java.awt.*;
  3. import java.awt.event.*;
  4. import javax.swing.*;
  5. import java.lang.Math;
  6. import java.awt.geom.*;
  7. import javax.swing.border.*;
  8. import javax.swing.event.*;
  9. import java.awt.event.MouseEvent;
  10. import java.net.*;
  11.  
  12. public class MatrixMultiplication extends Applet{
  13.  
  14.   Toolkit tk = Toolkit.getDefaultToolkit();
  15.   Dimension d = tk.getScreenSize();
  16.   Button continueButton = new Button("Continue");
  17.   JRadioButton two;
  18.   public int size = 2;
  19.   String name = new String("Matrix Multiplication:  2 x 2");
  20.   Button calculate = new Button("Calculate");
  21.  
  22.   public Button About = new Button("About");
  23.   public Button Help = new Button("Help");
  24.  
  25.   public void init() {
  26.     this.setBackground(Color.white);
  27.     Panel radioPanel = new Panel();
  28.     radioPanel.setBackground(Color.white);
  29.     radioPanel.setLayout(new GridLayout(9,1));
  30.     two = new JRadioButton("  2 x 2",true);
  31.     two.setBackground(Color.white);
  32.     ButtonGroup radioGroup = new ButtonGroup();
  33.     ButtonGroup radioGroup2 = new ButtonGroup();
  34.     radioGroup.add(two);
  35.     JLabel label = new JLabel("<html>Matrix Multiplication</html>");
  36.     JLabel label2 = new JLabel("<html>Please click continue to simulate</html>");
  37.     radioPanel.add(label);
  38.     radioPanel.add(label2);
  39.     radioPanel.add(two);
  40.     add(radioPanel);
  41.     setLayout(new FlowLayout(FlowLayout.CENTER));
  42.     add(continueButton);

  179.     // End of variables declaration
  180.  
  181.   }
  182. }
I know...the code is a mess...!I can't figure out.
Why doesn't work?
I'm so desperate that I even thought on asking the same thing on experts-exchange but I dunno if they're going to come out with some answer, and I have to pay for it
So any help would be great guys.
Thanks

come back in a few years. Maybe we'll have run out of more urgent matters by then and have time to help you.
As people are clearly allowed to attack me but I'm not allowed to defend myself, I no longer post to this site.

I just asked for help...! Nothing more
Doesn't mean that everything has to stop just because this is urgent.

Well I asked if anyone could help me with some code for an animation of a data flow within a system.
I got a reply from a guy called "Phaelax" and his post was like this "You want code given to you, use google. We're not here to do your work"
WTF. I came to this forum to ask for help and not to get a rude answer from some <snipped>who can't keep his mouth shut.
