Question

The 2d boolean is a static variable if that means anything. I thought that I could refer to just the name of the array, but I get an error for doing that.

public class Game {

static boolean[][] board = new boolean[3][3];
}

public class Computer
{
  if (Game.board = true)
    {
        //code
    }
}

Answer 1

if(Game.board = true) will throw a compiler error because board is a two-dimensional array and thus cannot be assigned a single boolean value.

Also, when comparing make sure you use the comparison operator ==

Perhaps, you want to do something like:

if(Game.board[i][j] == true) where i and j are indexing the array:

for (int i = 0; i < 3; i++)
{
    for (int j = 0; j < 3; j++)
    {
        if(board[i][j] == true)
        {
          // Code
        }
    }
}

You have board declared as static, any particular reason?

Since board[i][j] returns a boolean value, there really isn’t a need for the == true:

if(board[i][j])
