java - Want a multidimensional array but get a null pointer exception

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

It's been a while since I've so much as looked at Java, but have you tried doing this first?

board[0][0] = new hexagon(); // or whatever its constructor is
