Unable To Fill Blank Squares On Minesweeper Game

I'm having trouble filling in the blank squares on a Minesweeper game. What I am trying to is, if a user clicks a square and that square(s) does not have a bomb in it, or adjacent to it, should be set to an empty square.

Here's my recursive method below:

public void revealZeros(){
for(int x = -1; x <= 1; x++)
for (int y = -1; y <= 1; y++){
Square zeroSquare = (Square)board.getSquareAt(xLocation+x, yLocation+y);
if (!(zeroSquare.SquareHasBomb)){
setImage("images/empty.jpg");
}
}
revealZeros();
}

I am traversing around the square that the user clicks on with the use of two for-loops. Getting the square at that location and then applying an empty square image. On that square.

The function should then recurse itself and go onto the next square, if the next square does not have a bomb or does not have an adjacent bomb.

I keep on getting an infinite recursion problem
