Hi all,
I am a student and I have a project due 20th of this month, I mean May 20, 2007 after 8 days. The project is about creating a Connect Four Game. I have found some code examples on the internet which helped me little bit. But there are lot of problems I am facing developing the whole game. I have drawn the Board and the two players can play. The players numbers can fill the board, but I have problem implementing the winner for the game. I need to implement the hasWon() method for Horizontal win, Vertical win and Diagonal win. I also found some code examples on the net but I was unable to make it working. I have 5 classes and one interface which I m implementing. The main problem is how to implement the hasWon() method in the PlayGame class below with Horizontal, vertical and diagonal moves.
Sorry there is so much code.
This the interface I must implement, but now I am only implementing the int move() of this interface. I will implement the rest later after solving the winner problem with your help.
Interface code........... ...
interface Player {
void init (Boolean color);
String name ();
int move ();
void inform (int i);
}
Player1 class.......... ............
import java.util.*;
import java.io.*;
import javax.swing.*;
public class Player1 implements Player
{
public Player1()
{}
public int move()
{
Scanner scan = new Scanner(System. in);
// BufferedReader stdin = new BufferedReader (new InputStreamRead er(System.in));
int player1;
System.out.prin tln ("What is your Number, player 1?");
player1 = scan.nextInt();
System.out.prin tln ("Hey number"+player1 +" are you prepared to CONNECT FOUR");
System.out.prin tln();
return player1;
//Player.move();
//return player1;
}//end move method
public void init (Boolean color)
{}
public void inform (int i)
{}
public String name()
{
return "Koonda";
}
}//end player1 class
Player2 class.......... ............... ..
import java.util.*;
import java.io.*;
import javax.swing.*;
public class Player2 implements Player
{
public int move()
{
//int cup0,cup1,cup2, cup3,cup4,cup5, cup6;
// cup0=5;cup1=5;c up2=5;cup3=5;cu p4=5;cup5=5;cup 6=5;
//int num1, num2;
Scanner scan = new Scanner(System. in);
// BufferedReader stdin = new BufferedReader (new InputStreamRead er(System.in));
int player2;
System.out.prin tln ("What is your Number, player 2?");
player2 = scan.nextInt();
System.out.prin tln ("Hey "+player2+" are you prepared to CONNECT FOUR");
System.out.prin tln();
//return player1;
return player2;
}//end move method
public void init (Boolean color)
{}
public void inform (int i)
{}

I am sorry for all this junk code but I only understand it this way. Your urgent help is required. Looking forward to your reply.
Thanks in advance.
