Question

  1 public class TestWin{
  2     public static void main(String[] args){
  3         int n;
  4         hexagon[][] board;
  5
  6         n = 4;
  7         board = new hexagon[n][n];
  8         board[0][0].value = 'R';

Hi. javac doesn’t like what I did on line 8. Does anyone know why?

Answer 1

Spot on kwatford. All you have done with line 7 is to tell java to create space for n*n Hexagon objects in a 2 dimensional array.

You will still need to call new for each of these Hexagons

Essentially, you need to replace line 7 with something like:

board = new Hexagon[n][n];
for(int i=0; i<n; i++)
    for(int j=0; j<n; j++)
        board[i][j] = new Hexagon();
