Question about the task

Under discussion

Why do i have this error : error: 'void' type not allowed here for(GameObject neighbor : getNeighbors(gameField[y][x])) { Line 172. I dont get its a for loop... why the error?

The game is won when the number of remaining hidden cells is equal to the number of mines. To count the number of hidden cells, we'll introduce another variable whose initial value is equal to the total number of cells on the playing field. The value of this variable will decrease as the cells are revealed. When it becomes equal to the number of mines, the game is won.

In the event of a win, our game currently does nothing, but it should. It's time to fix that.

Let's write a win() method that stops the game and displays a beautiful congratulatory message to the winner.

Run the game and check that the win() method is run when the player wins.

Note that the win() method is called if the number of hidden cells is equal to the number of mines on the field. However, if the last revealed cell is a mine, then the method must not be called.

Requirements:

The MinesweeperGame class must have a private int countClosedTiles field that is initialized to SIDE * SIDE when it is declared.
The openTile(int, int) method must decrease the countClosedTiles field by 1 if the gameField element's isOpen flag is set.
The MinesweeperGame class must have a private void win() method.
The win() method must set the isGameStopped variable to true.
The win() method must call the showMessageDialog(Color, String, Color, int) method.
The openTile(int, int) method must call the win() method if the number of hidden cells is equal to the number of mines on the field and the last revealed cell is not a mine.

package com.codegym.games.minesweeper; public class GameObject { public int x; public int y; public boolean isMine; public int countMineNeighbors; public boolean isOpen; public boolean isFlag; public GameObject(int x,int y, boolean isMine){ this.x = x; this.y = y; this.isMine = isMine; } }

getNeighbors method returns void. You can't use void in the loop.

for(GameObject neighbor : getNeighbors(gameField[y][x])) {
