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_carpinel_compsys_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:
import java.applet.*;
import java.awt.*;
import java.awt.event.*;

Button calculate = new Button("Calculate");
public Button About = new Button("About");
public Button Help = new Button("Help");

this.setBackground(Color.white);

radioPanel.setBackground(Color.white);
radioPanel.setLayout(new GridLayout(9,1));
two = new JRadioButton(" 2 x 2",true);
two.setBackground(Color.white);
ButtonGroup radioGroup = new ButtonGroup();
ButtonGroup radioGroup2 = new ButtonGroup();
radioGroup.add(two);
JLabel label = new JLabel("<html>Matrix Multiplication</html>");
JLabel label2 = new JLabel("<html>Please click continue to simulate</html>");
radioPanel.add(label);
radioPanel.add(label2);
radioPanel.add(two);
add(radioPanel);
setLayout(new FlowLayout(FlowLayout.CENTER));
add(continueButton);

}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
