implementing objects in a private class to an array constructor...

[Johnny Steele]

hey everyone. So i'm working on my own version of mineSweeper. My professor's explanation, even after several times asking, doesn't seem to quite click with me. In the following code, I have to implement the MineSweeper constructor and my needed instance variable in it. So I've been told the constructor is taking an array of GameSquare objects. My question is: how do I initialize the information within each object if the GameSquare class if Private? Then, how do I call this array later in order to set the my other methods such as isFlagged, click, and so on? Just need a push in the right direction and some clarity, I'm quite confused. Thanks!!! Oh, this method is being implemented in such a way so that I can do some unit testing. There is another constructor using a random number generator but I believe the point of this one is testing.

public class MineSweeper {

  private class GameSquare {

    private boolean isMine;
    private int row;
    private int col;
    private boolean isVisible;
    private boolean isFlagged;
    private int mineNeighbors;

    // Construct a GameSquare object with all values set except mineNeighbors
    public GameSquare(boolean isMine, int row, int col) {
      this.isMine = isMine;
      this.row = row;
      this.col = col;
      isVisible = false;
      isFlagged = false;
      mineNeighbors = 0; // Use setAdjacentMines to set this instance variable
    }

    // After determining the number of mines around any GameSquare, set the number of surrounding mines 
    private void setAdjacentMines(int neighborCount) {
      this.mineNeighbors = neighborCount;
    }
    
  }

  // Represent all GameSquare objects where each knows its row, column,
  // number of mines around it, if it is a mine, flagged. and visible
  private GameSquare[][] board;

  /**
   * Construct a MineSweeper object using a given mine field represented by an
   * array of boolean values: true means there is mine, false means there is not
   * a mine at that location.
   * 
   * @param mines
   *          A 2D array to represent a mine field so all methods can be tested
   *          with no random placements.
   */
  public MineSweeper(boolean[][] mines) {
    // TODO: Complete this constructor first so you get a copy of a preset mine
    // field stored in this object.  Develop your own private inner class named
    // GameSquare to store all info about one square on the board such as row,
    // column, if it's flagged, visible, or is a mine. Also storing the 
    // number of adjacent mines around each GameSquare should be done here.
	  
	  
	  
	  int neighbors;
	  
	  for (int row = 0; row < mines.length; row++ ) {
		 for (int col = 0; col < mines[row].length; col++ ) {
			 board = mines[row][col];
			 }
				 
				 
			  neighbors = getAdjacentMines(row, col);
			  board.setAdjacentMines(neighbors);
			  
		 }
			 
			 
	 }
  }

as you can see I started but have no idea what i''m doing.
-Thank you ahead of time.

I found that I had to instantiate all the variables in the private class. Took me a while to figure out!!!

public MineSweeper(boolean[][] mines) {
   
	 
	  board = new GameSquare[mines.length][mines[0].length];
	  
	  for (int row = 0; row < mines.length; row++ ) {
			 for (int col = 0; col < mines[row].length; col++ ) {
				 board[row][col] = new GameSquare(mines[row][col] , row, col);
			    

			     
			 }  
	  }
