SOMEONE PLEASE HELP MEEE gr 12 java

[Kevin]

my program is the game of othello. i need help its due tmrw im rushing it last minute. i know its wrong. but i need help. basically the method is suppost to check if the block above it is the oposite color and if it is check if the one above it is the same color as urs.
i know its a poor explanation but the problem is in the "Checkvalid" method.

[Kevin]

Heres the code:


// The "GameBoard" class.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.applet.*;

public class GameBoard extends Applet implements ActionListener
{

int board[] [] = new int [10] [10];
JFrame gameFrame;
JPanel center;
JButton button[] [] = new JButton [8] [8];
boolean checkValid;

public GameBoard ()
{
checkValid = false;
for (int r = 0 ; r < 10 ; r++)
{
for (int c = 0 ; c < 10 ; c++)
{
board [r] [c] = 0;
}
}
board [4] [4] = 1; // white
board [4] [5] = 2; // black
board [5] [5] = 1;
board [5] [4] = 2;
gameFrame = new JFrame ("OTHELLO");
gameFrame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);

center = new JPanel ();
center.setBackground (Color.BLACK);
center.setLayout (new GridLayout (0, 8, 1, 1));

1. This should be in the Java Help section.
2. Use syntax tags:

code:

[syntax="Java"]Your code[/syntax]

3. Sorry I don't know much Java so I can't really help you.

well first off, you can get rid of a massive chunk of code with two for loops... When you have to copy and paste something 20 times, your doing something wrong.

button [0] [7] = new JButton (" ");
button [0] [7].setBackground (Color.red);
button [0] [7].setActionCommand ("button[0][7]");
button [0] [7].addActionListener (this);

code:

for y=0;y<8;y++     for x=0;x<8;x++         button[x][y] ....     end for end for

Same with your other code...

code:

for y=0;y<8;y++     for x=0;x<8;x++         if event.equals ("button[x][y]")             squarex = x + 1             squarey = y + 1         end if     end for end for

When you copy and paste code, your probably following a pattern, which usually means you can use a loop.

As for your actual problem... not sure.

Good thing I learned Othello recently .

I notice your program doesn't support capturing multiple pieces at a time. That's not good.

Programming is one class you CANNOT procrastinate in. I'm lucky, I enjoy it enough that it's not work for me.
