How to iterate over 2D array wrapped in the object of different class

[shean1488]

Hi everybody.

I have a class Sudoku. And puzzle stores 2D array of type Cell.

public class Sudoku implements Iterable<Cell []>
{
  private Cell [] [] puzzle;

What I want to do is to iterate through the puzzle in different class (SudokuValidator):

public class SudokuValidator
{
  private Sudoku puzzle;

how can I do this?
So I would like to get something like

puzzle[row][col]

[zeroliken]

you can access the array by either using a constructor or a method that contains the puzzle[row][col] at its class

The normal pattern with a base clas and another that depnds on it (eg model & view) goes like this:

public static void Main(..) {
 Sudoku  theGame = new Sudoku ();
 SudokuValidator v = new SudokuValidator(theGame);

...
then in the constructor for SudokuValidator you take the instance of Suduku as a parameter and keep a copy
